The article was titled 《Degradation of UV filter BP-1 with nitrogen-doped industrial graphene as a metal-free catalyst of peroxymonosulfate activation》, and you may find the article in Chemical Engineering Journal (Amsterdam, Netherlands).Application In Synthesis of Triacetonamine The information in the text is summarized as follows:

Instead of previously reported graphene oxide (GO), industrial graphene (reduced graphene oxide (IrGO)) was annealed with a nitrogen precursor. The obtained nitrogen-doped graphene (N-IrGO) was then employed as a novel catalyst for peroxymonosulfate (PMS) activation to degrade benzophenone-1 (BP-1) for the first time. The results show that N-IrGO exhibits excellent catalytic performance over conventional GO and its nitrogen-doped sample and was even better than the metal catalysts Co3O4 and Fe3O4. The enhanced catalytic performance might be attributed to graphitic-like nitrogen. Moreover, the effects of various factors were studied, including catalyst load, PMS concentration and reaction temperature Possible degradation pathways of BP-1 in the N-IrGO/PMS system were proposed based on detected intermediates and the frontier electron d. calculation Radical quenching experiments and ESR (EPR) tests indicated that nonradical oxidation (singlet oxygen (1O2)) plays a dominant role in the BP-1 degradation, in contrast to the previously proposed radical process. Finally, mineralization and stability experiments confirmed that N-IrGO may be an alternative catalyst for environmental remediation. This study contributes to designing novel graphene materials with N doping and gives new insight into nonradical oxidation on benzophenone-type UV filters degradation The results came from multiple reactions, including the reaction of Triacetonamine(cas: 826-36-8Application In Synthesis of Triacetonamine)

The article was 《Degradation of enrofloxacin in aqueous by DBD plasma and UV: Degradation performance, mechanism and toxicity assessment》. The article mentions the following:

Enrofloxacin (ENRO) as a highly toxic antibiotic poses great threats to human health and environmental safety. In this study, a novel technol. of coupling dielec. barrier discharge (DBD) and UV was investigated to efficiently degrade ENRO in aqueous, and had a higher degradation rate. The ENRO degradation rate achieved approx. 93.9% at 30 min, and approx. 1.20 g kWh-1 of energy yield (G50) was observed for the combined system. The addition of H2O2 and K2S2O4 improved the ENRO degradation due to the generation of ·OH and ·SO42-. In the presence of NO3-, the ENRO degradation played a tendency to promote first and then decrease, and the presence of SO42-resulted in the pos. effect, while the neg. effect was shown in the presence of Cl- and CO32-. The trapping experiment indicated that ·OH played an important part in the ENRO degradation The addition of UV into the DBD system decreased H2O2 concentration in deionized water, and increased ·OH concentration The DFT anal. showed the degradation mechanisms of ENRO at a mol. level. The degradation of ENRO mainly involved the oxidation of the piperazine group, the removal of Et acetate and the substitution of the F atom. The toxicity of ENRO and its degradation intermediates was evaluated. After reading the article, we found that the author used Triacetonamine(cas: 826-36-8Synthetic Route of C9H17NO)

The article was 《Activation of peroxydisulfate by defect-rich CuO nanoparticles supported on layered MgO for organic pollutants degradation: An electron transfer mechanism》. The article mentions the following:

Heterogeneous activation of peroxydisulfate (PDS) by transition metal oxides offers a promising strategy for organic pollutants removal but suffers from low electron transfer efficiency. Herein, layered MgO supported CuO nanoparticles was prepared by thermal conversion of metal-phenolic networks of Cu2+/Mg2+ and tannic acid. CuO nanoparticles (≈2 nm) were spatial monodispersed on layered MgO, inducing the formation of electron deficient Cu3+ and surface oxygen vacancies and thus facilitated adsorption and activation of PDS. The electron-rich CuO/MgO hybrid catalysts manifested good catalytic performance of PDS activation for organic pollutants removal. At 0.18 g/L of CuO/MgO hybrid catalyst and 0.2 mM of PDS, complete removal of bisphenol A (BPA) was achieved with a high kinetic constant (0.1 min-1, 50 min). Quenching experiments, ESR tests, PDS decomposition behaviors, electrochem. anal. and in situ ATR-FTIR and Raman spectroscopy revealed a nonradical pathway of electron transfer for PDS activation. The CuO/MgO hybrid catalysts exhibited wide working pH range from 3 to 11, selective oxidation capability, good resistance to halide ion and high utilization efficiency of PDS, and thus would be a promising candidate for wastewater remediation.

Sun, Qianqian; Liu, Bin; Wang, Zhao; Feng, Lili; Zhao, Ruoxi; Dong, Shuming; Dong, Yushan; Zhong, Lei; Gai, Shili; Yang, Piaoping published their research in Chemical Engineering Journal (Amsterdam, Netherlands) on December 1 ,2021. The article was titled 《H2O2/O2 self-supplementing and GSH-depleting Ca2+ nanogenerator with hyperthermia-triggered, TME-responsive capacities for combination cancer therapy》.Application In Synthesis of Triacetonamine The article contains the following contents:

The tumor microenvironment (TME) is complex in composition and unique in nature, and is closely related to the growth, invasion and metastasis of tumor cells. Improving and remodeling the TME to return it to a normalized state can fundamentally disrupt the environment and/or nutrient supply on which tumor cells depend. To achieve this goal, based on the unique physicochem. properties and biol. effects of CaO2, we designed and constructed a Ca2+ nanogenerator (named as CaO2-Cu/ICG@PCM) that enables H2O2/O2 self-supplementation and GSH depletion. The 808 nm laser induces the heat generation of photosensitizer indocyanine green (ICG) to initiate a series of reactions, followed by the production of copper ions, H2O2, O2 and large amounts of Ca2+, which can eventually lead to the combined treatment of photodynamic therapy (PDT), chemodynamic therapy (CDT) and calcium overload. Addnl., the reaction process is accompanied by the generation of Ca(OH)2, which greatly improves the acidic environment of TME and effectively promotes the oxidation process of GSH by H2O2, achieving the purpose of remodeling TME. It is worth mentioning that a large amount of free Ca2+ accumulating in tumor cells can rapidly initiate the process of calcium overload and calcification, which can not only play a role in tumor suppression, but also assist CT imaging to detect the effect of treatment. Thus, CaO2-Cu/ICG@PCM could be a promising candidate for bioimaging and tumor therapy.

In order to achieve enhanced treatment of swine wastewater as well as resource recycle, in this work, we applied coagulation treatment on swine wastewater by adding Fe and Mg ions, MgFe layered double hydroxides (LDHs) was yielded during coagulation process and the coagulation sludge was recycled to prepare biochar composite catalyst. The removal rates of total phosphorus (TP) and COD (COD) by Mg-Fe coagulation could achieve 82.55% and 98.51%, which is higher than that by coagulation with individual Mg2+ or individual Fe3+. Finely dispersed MgFe-LDHs flocculation was formed during the coagulation process and was embedded within zoogloea, suspended particles, organic matters, etc. The obtained coagulation sludge was recycled to prepare biochar composite catalyst by oxygen-limited pyrolysis. Redox reaction of iron compounds and electron shuttles capacity of biochar in the catalyst could activate potassium peroxymonosulfate (PMS) to generate ·OH, ·OOH and 1O2, which was responsible for catalysis potential. The as-prepared biochar composite catalyst showed satisfactory catalytic degradation capacity on tylosin and rhodamine B (pH value varied from 3 to 10), and the maximum degradation rate achieved 92.2% for tylosin and 81.9% for rhodamine B (RhB). Coagulation treatment of swine wastewater and in-situ formed layered double hydroxides recycling was suitable in wastewater treatment and resource recycling, of which the degradation rates of RhB were above 83% after five cycling experiments In general, the combined process exhibits great potential for the deep treatment of swine wastewater and resource recycling for sludge.

meeting severe environmental problems, highly efficient, environment-friendly, multiple reusable catalysts are demanding to develop. this work prepared C-based bimetallic oxides with O vacancies for peroxymonosulfate activation to degrade 4-aminobenzoic acid Et ester (ABEE). among different molar ratios of Fe2+ and Mn ions, Fe1Mn1-Fe NC had the optimum catalytic performance. ABEE degradation should have free radical and non-free radical pathways. all sulfate, hydroxyl, and superoxide radicals and singlet oxygen were responsible for efficient ABEE degradation and mineralization. lattice O was the main reactive site for ABEE degradation electron transport provided a good synergistic redox reaction between Fe and Mn and promoted lattice O release. a proposed pathway for ABEE degradation included electrophilic and radical addition, H-abstraction reaction, and diazotization. this work was expected to provide rational design of bimetallic materials with oxygen vacancies for in-situ environmental remediation.

The article was written by Shen, Minxian; Huang, Zhujian; Luo, Xuewen; Ma, Yujia; Chen, Chengyu; Chen, Xian; Cui, Lihua. The article contains the following contents:

Fenton reaction is widely used as a unique oxidation method for industrial wastewater treatment; however, it generates a massive amount of Fe sludge, which mostly contains other hazardous heavy metal wastes which can harm the environment and humans. This work proposed a sustainable method to eliminate side effects of the Fenton reaction and to transform Cu-containing Fenton sludge into an efficient catalyst for peroxymonosulfate (PMS) activation for tetracycline (TC) degradation The existence of Cu, which can increase sludge O2 vacancies, was attributed to the activation efficiency compared to Fe sludge with no Cu. X-ray diffraction and XPS results showed Fe is present as α-Fe2O3 and γ-Fe2O3; Cu mostly exists as Cu2+. Catalyst and PMS doses, pH, and recycling time effect on PMS reaction was illustrated. OH-, SO4- O2-, and 1O2 were the critical reactive oxygen species. TC decomposes into CO2 and water through six possible pathway processes with these free radicals. Given its sustainable treatment and high catalytic efficiency, dealing with Fe sludge which contains heavy metals serves as a modal practice for harmful wastewater treatment and can be popularized for broader applications.

Wang, Yujiao; Wang, Li; Ma, Fang; You, Yongqiang published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《FeOx@graphitic carbon core-shell embedded in microporous N-doped biochar activated peroxydisulfate for removal of Bisphenol A: Multiple active sites induced non-radical/radical mechanism》.Name: Triacetonamine The author mentioned the following in the article:

The development of novel carbocatalysts with high activity and stability is important for the rapid degradation of emerging pollutants. Fe/N co-doped biochar (FeOx@GC-NBC) was innovatively synthesized with a pyrolytic carbonization method and then used as a functional peroxydisulfate (PDS) activator to degrade Bisphenol A (BPA). FeOx@GC-NBC with an optimized Fe/N ratio modification exhibited 23.16 and 8.65-fold great activity for BPA removal compared to pristine BC and N-doped BC, resp. Approx. 93% of total organic carbon (TOC) could be removed in the heterogeneous activation system. We attributed the excellent performance of FeOx@GC-NBC to the following attributes: i) a microporous carbon matrix with larger sp. surface area (1691.81 m2·g-1) was favorable for adsorption, exposure of catalyst active sites (e.g., Fe-Nx, Graphitic N) and electron-transfer; ii) the C-O-Fe bond and highly core-shell structure of graphitic nanosheets (FeOx@GC) enhanced the N retention ability and durability of the catalyst; iii) organics adsorption dominated by a “”pore-filling and π-π interaction”” mechanism effectively promoted BPA oxidation In acidic and neutral solutions, the radical oxidation (SO·-4and ·OH) processes were responsible for BPA decomposition In alk. solution, electron transfer, instead of 1O2 or a high-valent iron species, was the dominant pathway. This study proposes a simple and feasible strategy to synthesize the FeOx@GC-NBC catalyst, which provides insights into catalyst design and the internal active sites involved in the purification mechanism of refractory organics The experimental part of the paper was very detailed, including the reaction process of Triacetonamine(cas: 826-36-8Name: Triacetonamine)

Long, Yangke; Huang, Yixuan; Wu, Huiyi; Shi, Xiaowen; Xiao, Ling published their research in Chemical Engineering Journal (Amsterdam, Netherlands) on August 1 ,2019. The article was titled 《Peroxymonosulfate activation for pollutants degradation by Fe-N-codoped carbonaceous catalyst: Structure-dependent performance and mechanism insight》.Quality Control of Triacetonamine The article contains the following contents:

In this study, Fe-N-codoped carbonaceous catalysts (Fe-N-C-x) with different structures including one-dimensional carbon nanotubes (1D CNTs) and two-dimensional porous carbon sheets (2D NC) to three-dimensional carbon nanotubes/porous carbon sheets composites (3D CNTs/NC) were systematically synthesized and applied as peroxymonosulfate (PMS) activators. It was found that the Fe-N-C-x catalysts exhibited structure-dependent catalytic performance, following the order of 2D NC > 3D CNTs/NC > 1D CNTs, and also substrate-dependent degradation performance that the reaction kinetics varied greatly for different organic pollutants. Benefiting from the unique structure characteristic and high d. of active sites, 2D Fe-N-C-1 showed far superior catalytic performance than the generally used carbocatalysts with negligible Fe leaching. Besides, various influential factors affecting the catalytic performance were systematically investigated. Fe-N-C-1 showed high catalytic efficiencies toward a broad spectrum of organic pollutants, and it was confirmed that both radical and non-radical degradation pathways existed during pollutants degradation The competitive radical quenching tests and ESR measurements verified that the superoxide anion radical (OA·-2) was the primary reactive oxidized species for degradation of p-chlorophenol (4-CP). The chronoamperometry anal. demonstrated that Fe-N-C-1 facilitated the electron transfer from 4-CP to PMS, resulting in the degradation of 4-CP through a non-radical mechanism. Our result not only reveals the structure-dependent PMS activation performance of transition-metal and nitrogen codoped carbocatalysts but also provides solid evidence that the defect-rich carbon materials with amorphous carbon and partial graphitic structure also favor the electron transfer mechanism.

The article was written by Tan, Yixuan; Ma, Yihan; Fu, Sheng; Zhang, Aiqing. The article contains the following contents:

Photodynamic antibacterial therapy has been considered as one of the most promising treatments to alleviate the spread of multidrug resistant bacterial pathogens. Given the hypoxic environment of infectious tissues, photosensitizers with reduced oxygen-demand could exhibit superiority upon irradiation Herein reported is a novel C70-based photosensitizers synthesized by the facile one-step thiol-ene reaction. Various characterization techniques were employed to confirm the structural, photoluminescent properties, photostability and biocompatibility of the as-synthesized C70-COOH nanoparticles. Furthermore, they were capable of efficiently producing reactive oxygen species following both the type I and II mechanistic pathways, thus still generating adequate free radicals under hypoxic condition. Therefore, they could approach and destroy the bacterial cell membrane in the presence of visible light, thereby causing cytoplasmic leakage and eventually achieving broad-spectrum inactivation of four representative bacterial strains. Especially, methicillin-resistant Staphylococcus aureus (MRSA) were completely eliminated after merely 10 min irradiation, and the formation of its corresponding biofilm were also greatly inhibited by C70-COOH nanoparticles. These results provide new insights and opportunities for the development of hypoxia-tolerant fullerene-based photosensitizers to combat multidrug resistant bacterial and related infections.
