Li, Qianqian;Huang, Xinchen;Su, Guijin;Zheng, Minghui;Huang, Chunhua;Wang, Mengjing;Ma, Chunyan;Wei, Da research published 《 The Regular/Persistent Free Radicals and Associated Reaction Mechanism for the Degradation of 1,2,4-Trichlorobenzene over Different MnO₂ Polymorphs》, the research content is summarized as follows. The role of regular/persistent free radicals on the catalytic activity of K⁺-tuned MnO₂ tunnel structures is poorly understood to date. Herein, three MnO₂ polymorphs (α-, β-, and δ-MnO₂) were synthesized and examined toward the degradation of 1,2,4-trichlorobenzene (1,2,4-TrCBz) at 300 °C. δ-MnO₂, with a two-dimensional-layered tunnel structure tuned by K⁺, exhibited the highest activity among the three MnO₂ polymorphs. The ESR spectroscopy results confirmed that δ-MnO₂ featured the most abundant reactive oxygen species (ROS: O₂^-•, •OH, and ¹O₂), followed by α-MnO₂ (O₂^-• and ¹O₂), and β-MnO₂ (O₂^-•), being supported by the calculated energy barrier. It was, intriguingly, noted that persistent organic free radicals, newly recognized as emerging surface-stabilized compound, were remarkably detected in α- and β-MnO₂/1,2,4-TrCBz systems but not in more reactive δ-MnO₂/1,2,4-TrCBz system. These might contribute to discrepant oxidative degradation process. During the oxidative process, intermediates, including benzoic acid and glycerol, formed via attack by ROS. Upon further attack, these intermediates fragmented into smaller mols. such as formic, acetic, propionic, and butyric acids. The present findings give deeper insights into the role of free radicals on the catalytic degradation of chlorinated aromatics

Li, Tiantian;Huang, Yu;Wei, Gaoliang;Zhang, Ya-nan;Zhao, Yuanhui;Crittenden, John C.;Li, Chao research published 《 Quantitative structure-activity relationship models for predicting singlet oxygen reaction rate constants of dissociating organic compounds》, the research content is summarized as follows. As singlet oxygen (¹O₂) is ubiquitous in the environment, ¹O₂-involved oxidation may play an important role in the transformation and fate of organic pollutants. Accordingly, the reaction rate constants (k_1O2) of organic compounds with ¹O₂ are important to determine the environmental fate and persistence assessment of organic pollutants. However, currently there are limited k_1O2 data available, especially for organic chems. with different charged (deprotonated/protonated) forms. Herein three quant. structure-activity relationship (QSAR) models (one comprehensive model and two models for neutral and deprotonated mols.) were created for predicting aqueous k_1O2 values for diversely dissociating mols. The models include larger datasets (180 chems.) and have wider applicability domain than previous ones. Mol. structural characteristics (only half-wave potential is present in both models) determining the ¹O₂ reaction rate of neutral and deprotonated mols. vary greatly. The comparison results of predicting k_1O2 values of organic compounds at certain pH conditions show that the combination of the QSAR models for neutral and deprotonated mols. has advantages over the comprehensive QSAR model. This work is the first study to predict k_1O2 for a wide variety of neutral and deprotonated mols. and provides an important tool for assessing the fate of organic pollutants in aquatic environments.

Leukocyte activation and the resulting oxidative stress induced by bioincompatible materials during hemodialysis impact the prognosis of patients. Despite multiple advances in hemodialysis dialyzers, the prognosis of hemodialysis patients with complications deeply related to oxidative stress, such as diabetes mellitus, remains poor. Thus, we re-evaluated the effects of hemodialysis on multiple reactive oxygen species using ESR-based methods for further improvement of biocompatibility in hemodialysis. We enrolled 31 patients in a stable condition undergoing hemodialysis using high-flux polysulfone dialyzers. The effects of hemodialysis on reactive oxygen species were evaluated by two methods: MULTIS, which evaluates serum scavenging activities against multiple hydrophilic reactive oxygen species, and i-STrap, which detects lipophilic carbon-center radicals. Similar to previous studies, we found that serum hydroxyl radical scavenging activity significantly improved after hemodialysis. Unlike previous studies, we discovered that scavenging activity against alkoxyl radical was significantly reduced after hemodialysis. Moreover, patients with diabetes mellitus showed a decrease in serum scavenging activity against alkyl peroxyl radicals and an increase in lipophilic carbon-center radicals after hemodialysis. These results suggest that despite extensive improvements in dialyzer membranes, the forms of reactive oxygen species that can be eliminated during dialysis are limited, and multiple reactive oxygen species still remain at increased levels during hemodialysis.

Hobich, Jan;Huber, Birgit;Theato, Patrick;Mutlu, Hatice research published 《 Acyclic Diene Metathesis (ADMET) Polymerization of 2,2,6,6-Tetramethylpiperidine-1-sulfanyl (TEMPS) Dimers》, the research content is summarized as follows. The preparation of polymers containing sulfur-nitrogen bond derivatives, particularly 2,2,6,6-tetramethylpiperidine-1-sulfanyl (TEMPS) dimers (i.e., BiTEMPS), has been limited to free-radical or conventional step-growth polymerization as result of the inherent thermal lability of the BiTEMPS unit. Accordingly, a novel poly(diaminodisulfide) possessing the BiTEMPS functional group is synthesized via acyclic diene metathesis (ADMET) polymerization at 65-75°C within 3 h with precise control over the primary polymer structure. Polymer is isolated with an M_n of 20 400 g mol^-1 and ETH of 1.9. Importantly, detailed NMR, size exclusion chromatog., attenuated total reflectance Fourier transform IR (ATR-IR) in addition to elemental anal. studies of the BiTEMPS polymer confirm the successful polymerization, and show that the BiTEMPS unit remains intact during the polymerization process. Furthermore, the previously unexplored UV-responsiveness of the BiTEMPS decorated polymer backbone is investigated for the very first time.

Hu, Yi;Chen, Dezhi;Wang, Shoujun;Zhang, Rui;Wang, Yichuan;Liu, Meng research published 《 Activation of peroxymonosulfate by nitrogen-doped porous carbon for efficient degradation of organic pollutants in water: Performance and mechanism》, the research content is summarized as follows. Carbon materials are becoming the first choice for activating persulfate due to their environmental friendliness, high chem. stability, and metal-free leaching. However, the preparation of efficient carbon catalyst and the in-depth anal. for persulfate activation is still insufficient. Herein, N-doped porous carbons (NPCs) were prepared by the pyrolysis of polyacrylonitrile and used to trigger peroxymonosulfate (PMS) for degrading organic pollutants in water. The results showed that the optimized NPC-700, with large sp. surface area, rich pore structure, high content of pyridinic N and graphitic N, as well as excellent oxygen-containing functional groups, possessed the best performance in activating PMS to degrade methylene blue (MB) with 99.15% degradation rate in 30 min. Furthermore, the NPC-700 delivered high stability under a wide pH from 3.51 to 11.15. The radical quenching experiments and ESR (EPR) spectroscopy revealed that ·OH, O₂^·- , SO₄ ^·- and ¹ O₂ active species were involved in the catalytic oxidation of MB. Besides, the NPC-700/PMS system exhibited excellent degradation performance for various organic dyes, including rhodamine B, acid orange 7, and methyl orange. This study not only provides a promising metal-free catalyst for the removal of organic pollutant in water, but also promotes the sustainable development of carbon-based materials.

In this study, CuO/HNTs were applied to activate persulfate (PS) to firstly degrade and mineralize TCS. The morphol., crystal structure, sp. surface and surface composition were characterized by SEM, TEM, BET, XRD and XPS. The exptl. parameters were optimized with 0.2 g/L CuO/HNTs and 2 mM PS. TCS was totally removed in 180 min under optimized conditions. The mechanism study using the quenching reaction, EPR, XPS and electrochem. demonstrated that even radical reactions (·OH and O·-2) pathway existed; the nonradical mechanism (1O2 and surface electron transport) was dominant to the efficient TCS degradation Using FT-ICR MS, the degradation intermediates were identified, and transformation pathways were proposed. The degradation intermediate studies indicated that TCS began to break from the aromatic ring containing monochlorine, and the Cl functional group was gradually substituted. CO2 and H2O were generated with breaking of ether bonds. The toxicity of the solution was also evaluated by the survival rate of the luminescent bacteria, and the toxicity of the solution decreased overall. A stability study showed that CuO/HNTs retained good crystal structure and degradation efficiency even after 5 cycles.

Eysseric, Emmanuel;Gagnon, Christian;Segura, Pedro A. research published 《 Identifying congeners and transformation products of organic contaminants within complex chemical mixtures in impacted surface waters with a top-down non-targeted screening workflow》, the research content is summarized as follows. Over 350,000 compounds are registered for production and use including a high number of congeners found in complex chem. mixtures (CCMs). With such a high number of chems. being released in the environment and degraded into transformation products (TPs), the challenge of identifying contaminants by non-targeted screening (NTS) is massive. “Bottom-up” studies, where compounds are subjected to conditions simulating environmental degradation to identify new TPs, are time consuming and cannot be relied upon to study the TPs of hundreds of thousands of compounds Therefore, the development of “top-down” workflows, where the structural elucidation of unknown compounds is carried directly on the sample, is of interest. In this study, a top-down NTS workflow was developed using mol. networking and clustering (MNC). A total of 438 compounds were identified including 176 congeners of consumer product additives and 106 TPs. Reference standards were used to confirm the identification of 53 contaminants among them lesser-known pharmaceuticals (aliskiren, sitagliptin) and consumer product additives (lauramidopropyl betaine, 2,2,4-trimethyl-1,2-dihydroquinoline). The MNC tools allowed to group similar TPs and congeners together. As such, several previously unknown TPs of pesticides (metolachlor) and pharmaceuticals (gliclazide, irbesartan) were identified as tentative candidates or probable structures. Moreover, some congeners that had no entry on global repositories (PubChem, ChemSpider) were identified as probable structures. The workflow worked efficiently with oligomers containing ethylene oxide moieties, and with TPs structurally related to their parent compounds The top-down approach shown in this study addresses several issues with the identification of congeners of industrial compounds from CCMs. Furthermore, it allows elucidating the structure of TPs directly from samples without relying on bottom-up studies under conditions discussed herein. The top-down workflow and the MNC tools show great potential for data mining and retrospective anal. of previous NTS studies.

Fang, Cunxia;Gao, Xingmin;Zhang, Xiangcheng;Zhu, Jiahui;Sun, Sheng-Peng;Wang, Xiaoning;Wu, Winston Duo;Wu, Zhangxiong research published 《 Facile synthesis of alkaline-earth metal manganites for the efficient degradation of phenolic compounds via catalytic ozonation and evaluation of the reaction mechanism》, the research content is summarized as follows. In this paper, we demonstrate the facile and general synthesis of alk.-earth metal manganites, denoted as A(Mg, Ca, Ba)Mn_xO_y, for efficient degradation of high-concentration phenolic compounds via catalytic ozonation. The representative CaMn_xO_y oxides show a hierarchical spherical structure constructed by crystalline nanorods and numerous macropores. They possess mixed Mn⁴⁺/Mn³⁺ chem. valences and abundant surface hydroxyl (OH) groups. The ozone (O₃) decomposition rate on the CaMn_xO_y catalysts is greatly accelerated and follows the first-order law. These catalysts are promising for the degradation of phenolic compounds via catalytic ozonation, exhibiting rapid pseudofirst-order degradation kinetics, a high total organic carbon (TOC) removal efficiency and an excellent stability. Under optimized conditions (a low O₃ dosage of 1.5 mg/min and a catalyst dosage of 7.5 g/L), for the treatment of concentrated phenol (50-240 mg/L), the CaMn_xO_y catalysts show 100% degradation and 50-70% mineralization within 1.0 h. The Ca²⁺ ions are essential to create redox Mn⁴⁺/Mn³⁺ couples and to significantly reduce manganese leaching. High surface ratios of Mn⁴⁺/Mn³⁺ and OH/lattice oxygen (O_lat) are beneficial for enhancing the catalytic performance. Superoxide anion free radicals (^·O^–₂) and singlet oxygen (¹O₂) are the predominant reactive species for the oxidation degradation The ^·O^–₂ reaction pathway is proposed. Specifically, the surface OH sites activate O₃, displaying highly enhanced decomposition rates. The generated ^·O^–₂ and ¹O₂ play a role in oxidation The redox Mn⁴⁺/Mn³⁺ and the O_lat/oxygen vacancy (O_lat/O_vac) couples play important roles in electron transfer. The proposed mechanism is supported by active site probing, radical scavenging, spectroscopic studies, and the results in the degradation of substituted phenols.
