Zheng, Weisheng;Sun, Yue;Gu, Yingpeng research published 《 Catalysis and adsorption of Zr-doped Fe₃O₄ nanoparticles provide a new strategy for diazinon removal and phosphorus recovery from aqueous solution》, the research content is summarized as follows. As potential persistent and toxic organic contaminants, organophosphorus pesticides (OPPs) are frequently detected in various waters. However, few studies are available on removing OPPs in aqueous solution through heterogeneous catalytic activated peroxymonosulfate (PMS). Herein, Zr-doped Fe₃O₄ magnetic nanoparticles were prepared via a facile solvothermal method and employed to activate PMS for degrading diazinon. A series of characterization and performance tests revealed that Zr_(0.3)Fe₃O₄ composite played a dual role as both adsorbent and heterogeneous catalyst for removal of diazinon. Attractively, the introduction of Zr into magnetite endowed the nanoparticles with prominent adsorption capacity for released phosphate during the oxidation reaction. Combined with ESR (EPR) spectra and quenching studies, Zr_(0.3)Fe₃O₄ effectively catalyzed PMS to produce four kinds of reactive oxygen species (ROS), and ¹O₂ and O^–₂ were dominantly responsible for diazinon degradation Furthermore, the possible degradation pathways of diazinon in Zr_(0.3)Fe₃O₄/PMS system were discussed based on liquid chromatog. mass spectrometry (LC-MS) anal. In conclusion, the Zr_(0.3)Fe₃O₄ nanoparticles can not only remove diazinon by catalytic oxidation but also immobilize degraded phosphorus, hence, this work offers a novel strategy for developing versatile composites.

Zheng, Wentian;Liu, Yanbiao;Liu, Wen;Ji, Haodong;Li, Fang;Shen, Chensi;Fang, Xiaofeng;Li, Xiang;Duan, Xiaoguang research published 《 A novel electrocatalytic filtration system with carbon nanotube supported nanoscale zerovalent copper toward ultrafast oxidation of organic pollutants》, the research content is summarized as follows. In this study, we designed an integrated electrochem. filtration system for catalytic activation of peroxymonosulfate (PMS) and degradation of aqueous microcontaminants. Composites of carbon nanotube (CNT) and nanoscale zero valence copper (nZVC) were developed to serve as high-performance catalysts, electrode and filtration media simultaneously. We observed both radical and nonradical reaction pathways, which collectively contributed to the degradation of model pollutants. Congo red was completely removed via a single-pass through the nZVC-CNT filter (τ <2 s) at neutral pH. The rapid kinetics of Congo red degradation were maintained across a wide pH range (from 3.0-7.0), in complicated matrixes (e.g., tap water and lake water), and for the degradation of a wide array of persistent organic contaminants. The superior activity of nZVC-CNT stems from the boosted redox cycles of Cu2+/Cu+ in the presence of an external elec. field. The flow-through design remarkably outperformed the conventional batch system due to the convection-enhanced mass transport. Mechanism studies suggested that the carbonyl group and electrophilic oxygen of CNT served as electron donor and electron acceptor, resp., to activate PMS to generate •OH and 1O2via one-electron transport. The electron-deficient Cu atoms are prone to react with PMS via surface hydroxyl group to produce reactive intermediates (Cu2+-O-O-SO-3), and then 1O2 will be generated by breaking the coordination bond of the metastable intermediate. The study will provide a green strategy for the remediation of organic pollution by a highly efficient and integrated system based on catalytic oxidation, electrochem., and nano-filtration techniques.

Zou, Lijun;Zhu, Xiaoying;Lu, Lun;Xu, Yiliang;Chen, Baoliang research published 《 Bimetal organic framework/graphene oxide derived magnetic porous composite catalyst for peroxymonosulfate activation in fast organic pollutant degradation》, the research content is summarized as follows. A magnetic nitrogen-doped porous carbon material (Co/CoOx@NC) with large surface area was synthesized for peroxymonosulfate (PMS) activation. The addition of reduced graphene oxide (rGO) remarkably improved the catalytic performance of Co/CoOx@NC due to its enhancement on graphitization degree and structural regulation. Co/CoOx@NC exhibited excellent PMS activation for phenol removal with almost 100% removal efficiency in 10 min, close to that of homogeneous Co²⁺. Simultaneously, good reusability and recyclability of Co/CoOx@NC was achieved, demonstrating its feasibility for practical application. The PMS activation process in Co/CoOx@NC/PMS system was dominant by efficient mediation of electron transfer from pollutants to PMS through the sp2-hybridized carbon and nitrogen network. Batch tests of various organic compounds removal revealed the specific selectivity related to the electron-donating ability in Co/CoOx@NC/PMS system. As the negligible role of reactive radicals on pollutants degradation, the inhibition of interfering species (e.g., Cl^–, natural organic matters) was largely weakened. Present study not only provided a strategy for rationally designing highly efficient nanocarbon-based catalysts on PMS activation, but also presented new insight into the mechanism of PMS heterogeneous activation.

Zuo, Shiyu;Li, Dongya;Guan, Zeyu;Zhu, Yi;Pu, Mengjie;Xia, Dongsheng research published 《 Rapid electron transfer boosts CuO-Mediated nonradical oxidation pathways for efficient removal of Bisphenol A》, the research content is summarized as follows. CO₂ emission reduction and CO₂ capture during wastewater treatment are the main objectives of carbon neutral wastewater treatment. Here, we show that CuO is expected to promote non-radical oxidation pathways through enhanced electron transfer. Calcination temperature may affect crystal growth and microscopic strain, and the smaller particle size of CuO provides shorter distance nanochannels for core-shell diffusion of electrons/defects. This facilitates fast electron transfer and easy in/out diffusion of electrons/defects, thus promotes ¹O₂-mediated nonradical oxidation (13.6-fold increase in kinetic reaction rate). A kinetic model was developed to predict the kinetic reaction rate constants of CuO/peroxymonosulfate (PMS) under different parameter conditions. The degradation pathways and product toxicity of pollutants are explored through Frontier MO Theory (FMO) and the Toxicity Estimation Software Tool (TEST). Due to the alk. environment and the mild oxidation capacity of ¹O₂-mediated nonradical oxidation pathway, CuO/PMS system can not only effectively detoxify toxic organic pollutants without complete mineralization (emitting large amounts of CO₂), but also capture CO₂ and convert it into stable carbonates for environmental use. This study demonstrates the ability of CuO/PMS to effectively treat toxic organic pollutants in a practical microreactor, and provides a viable pathway for carbon neutral wastewater treatment.

Yin, Xueqian;Zhang, Jie;Xu, Jiazhuang;Tian, Meng;Li, Luying;Tan, Lin;Li, Zhongming research published 《 Fast-acting and highly rechargeable antibacterial composite nanofibrous membrane for protective applications》, the research content is summarized as follows. Bacterial infection has been globally recognized as one of the most prominent public health safety concerns, and the untreated surfaces are highly susceptible to the bacterial deposition and breeding without protective covers, thus the fabrication of potent membranes for shielding and combating bacteria is of vital importance. In this study, a powerful nanofibrous membrane on inactivating bacteria was fabricated based on a N-halamine polymeric system, which included a hydrophobic thermoplastic polyurethane (TPU) and a hydrophilic modified polyacrylic acid (PAA), and the fabricated membrane was called as TPM. According to the systematic investigations, TPM exhibited excellent antibacterial and antivirus activity, the min. inhibitory concentration to E. coli and S. aureus was 1.4 mg/mL. Upon contact, above 95% of both bacteria (≈106 CFU/mL) could be killed within 5 min, and the antiviral activity rate of TPM reached to above 99.92%. TPM also possessed a rapid chlorine loading capacity, which could completely load the active chlorine within 1 h, and the loading content of active chlorine rarely reduced even after five chlorination-quenching cycles, indicating excellent regenerative chlorination capacity. Addnl., the antibacterial mechanism in terms of macromol. release, morphol. damage and the reduction of respiratory chain dehydrogenase activity were studied. The resulting TPM with superior antibacterial performance can serve as a scalable biocidal layer for protective applications, and the facile synthesis of the TPM may also provide a strategy to develop protective materials in a sustainable, rechargeable, and structurally adaptive form.

Due to the high theor. specific energy, the lithium-oxygen battery has been heralded as a promising energy storage system for applications such as elec. vehicles. However, its large over-potentials during discharge-charge cycling lead to the formation of side-products, and short cycle life. Herein, we report an ionic liquid bearing the redox active 2,2,6,6-tetramethyl-1-piperidinyloxy moiety, which serves multiple functions as redox mediator, oxygen shuttle, lithium anode protector, as well as electrolyte solvent. The additive contributes a 33-fold increase of the discharge capacity in comparison to a pure ether-based electrolyte and lowers the over-potential to an exceptionally low value of 0.9 V. Meanwhile, its mol. facilitates smooth lithium plating/stripping, and promotes the formation of a stable solid electrolyte interface to suppress side-reactions. Moreover, the proportion of ionic liquid in the electrolyte influences the reaction mechanism, and a high proportion leads to the formation of amorphous lithium peroxide and a long cycling life (> 200 cycles). In particular, it enables an outstanding electrochem. performance when operated in air.

Sludge-derived hydrochar (HC) and pyrochar (PC) by hydrothermal and pyrolytic treatments were compared their peroxydisulfate (PDS) activation capacities toward atrazine (ATZ) removal. The HC alone induced lower ATZ removal than PC alone. However, ATZ removal was significantly enhanced in HC/PDS system rather than in PC/PDS system. ATZ removal via adsorption was very low, and singlet oxygen (¹O₂) primarily contributed to its removal, independently on the PDS addition Compared to HC, PC possessed stronger electron transfer capacity, exhibiting a higher ATZ removal. After PDS addition, humic substances (HS) in HC (36.3 ± 2.4 mg/g) played a decisive role in enhanced ATZ degradation: PDS excited HS to a triplet state (³HS_*); then, PDS and ³HS* together yielded more ¹O₂. Meanwhile, ³HS* accelerated electron transfer on HC surface. Thus, more electrons were transferred from AZT to ¹O₂. However, function of small amount of HS in PC (1.5 ± 0.2 mg/g) could be ignored.

In this study, ball milling, a simple grinding method, were used to treat biochar, and the ball-milled biochar materials were used to activate peroxymonosulfate (PMS) for tetracycline (TC) removal. It was demonstrated that the ball-milled biochar materials using different ball mass ratios and ball milling time benefited the generation of oxygen-functional groups and defects on the surface, thereby enhanced the catalytic performance of biochar to degrade TC. Besides, the different exptl. conditions (initial pH, catalyst dosage, PMS dosage, and TC dosage) and coexisting substances all affected the degradation efficiency of TC. ESR and radicals quenching experiments showed that the radicals attached to the biochar contributed greatly to the degradation of TC, and both free radicals and non-free radicals participated in the TC degradation process.

The ACT removal rate constant in the presence of 5 mg/L FeSO₄·7H₂O (0.1099/min) was ∼20 times that in the absence of FeSO₄•7H₂O (0.0045/min) with 0.1 g/L MoS₂/FeSO₄·7H₂O at pH₀ 3. ESR characterization and quenching experiments suggested the key role of singlet oxygen (¹O₂), acting as dominant reactive species responsible for ACT degradation in the Fe²⁺/MoS₂/PMS system. The MoS₂ chem. state and composition, ion concentrations (Fe, Mo) concentrations, and Mo⁶⁺ speciation were examined Results suggested the Fe²⁺ promoting effect originated from Fe²⁺ regeneration mediated by MoS₂, and formation of the molybdenum(VI) peroxo complex species in the Fe²⁺/MoS₂/PMS system. This work provided insight into PMS activation by MoS₂ accelerated by Fe²⁺ and suggested a highly efficient, easy-to-handle, environment-friendly method to treat refractory wastewater.
