Luo, Haopeng;Zhou, Xin;Chen, Quanyuan;Zhou, Juan research published 《 Removal of 2,4-dichlorophenoxyacetic acid by the boron-nitrogen co-doped carbon nanotubes: Insights into peroxymonosulfate adsorption and activation》, the research content is summarized as follows. B, N co-doped CNTs were synthesized by a simple one-step thermal process and the advanced oxidation processes (AOPs) of 2,4-dichlorophenoxyacetic acid (2,4-D) over the catalyst involved peroxymonosulfate (PMS) activation was investigated. The co-doped catalysts showed higher isoelec. points (IEPs) than those of CNTs and single doped CNTs, facilitating the adsorption of PMS anion (HSO-5) on the catalyst surface, and the AOPs of 2,4-D depended on PMS concentration could be illustrated by the Langmuir-Hinshelwood model. The removal efficiency of 2,4-D over CNTs, CB450, CN450 and CBN450-2 was 20%, 23%, 34% and 68%, resp. The enhancement of catalytic activity was due to the synergistic effect between B and N dopants and both the pyrrolic N and B-N complex played roles in the catalytic reaction. The quenching test and ESR (EPR) results showed that 1O₂ contributed most to the oxidation of 2,4-D and the reaction experienced both the free radical and non-radical pathways. Addnl., the DFT calculation results showed that the adsorption energy of PMS on the surface N dopants decreased by B co-doping, implying that a moderate adsorption energy may facilitate the release of active species generated by PMS activation.

Luo, Tao;Peng, Ying;Chen, Long;Li, Jinjun;Wu, Feng;Zhou, Danna research published 《 Metal-free electro-activated sulfite process for As(III) oxidation in water using graphite electrodes》, the research content is summarized as follows. Transition-metal-activated sulfite [S(IV)] processes for water decontamination have recently received intense attention in the field of decontamination by advanced oxidation processes (AOPs). However, the drawback with respect to the secondary metal sludge contamination involved in various AOPs has been argued often. In this work, we developed a novel electro-sulfite (ES) process using stable and low-cost graphite electrodes to address that concern. Arsenite [As(III)] was used as the target compound for removal by the ES process because of its wide presence and high toxicity. Parameters, including cell voltage, S(IV) concentration, solution pH, and water matrix, and the mechanisms for reactions on anode and cathode were investigated in electrolytic cells containing one or two compartments, resp. The results show that the ES process using 1 mM S(IV) and 2 V cell voltage oxidizes 5μM As(III) at a rate of 0.127 min^-1, which is 15-fold higher than mere electrolysis without S(IV) addition (0.008 min^-1) at pH 7. Further studies using radical scavengers and ESR assays demonstrated that oxysulfur radicals (i.e., SO₅^•- and SO₄^•-) and HO^• are responsible for As(III) oxidation in the ES process. However, HO₂^• produced via the oxygen reduction reaction in the EO process plays a major role in As(III) oxidation, which explains the lower reaction rate in the absence of S(IV). The effectiveness of the ES process was moreover evidenced by 60-82% As(III) oxidation in field water within 40 min. Overall, this work realizes the metal-free activation of S(IV) and significantly leverages the S(IV)-based water treatment technologies.

Ma, Jianchao;Zhang, Siyu;Duan, Xiaoguang;Wang, Yuxin;Wu, Danlei;Pang, Jin;Wang, Xin;Wang, Shaobin research published 《 Catalytic oxidation of sulfachloropyridazine by MnO₂: Effects of crystalline phase and peroxide oxidants》, the research content is summarized as follows. Catalytic activation of different oxidants including peroxymonosulfate (PMS), peroxydisulfate (PDS), hydrogen peroxide (H₂O₂) and ozone (O₃) by MnO₂ for degradation of sulfachloropyridazine (SCP) was investigated and the effects of different crystalline phases of MnO₂ including nanowire α-MnO₂, nanorod β-MnO₂, nanofiber γ-MnO₂, and nanosphere δ-MnO₂ on catalytic ozonation of SCP were also studied. The SCP degradation and total organic carbon removal indicated that the oxidation efficiency of the peroxide oxidants followed an order of O3/MnO₂ > PMS/MnO₂ > PDS/MnO₂ > H₂O₂/MnO₂. In catalytic ozonation, SCP degradation rate constants of different MnO₂ phases followed an order of δ-MnO₂ > α-MnO₂ > γ-MnO₂> β-MnO₂. ESR (EPR) suggested that hydroxyl radicals (·OH) and singlet oxygen (¹O₂) might be more significant for SCP degradation than sulfate (SO·^–₄) and superoxide (·O^–₂) radicals. Radical competition experiments demonstrated that ¹O₂ and ·OH contributed to 63.16% and 28.07%, resp., for the catalytic ozonation of SCP. It was also found that more oxygen vacancies, sp. surface area and exposure of MnO₆ edges could facilitate the activation of O₃ for ¹O₂ and ·OH productions and SCP degradation The degradation pathways of SCP could mainly follow the cleavage of S-C or S-N bond and dechlorination, accompanied by hydroxylation and oxidation

The core-shell Fe2O3@CoFe2O4 hybrids microspheres with abundant oxygen vacancies were synthesized through in-situ ion exchange-calcination method and employed to induce peroxymonosulfate (PMS) to eliminate organic pollutants. The superior catalytic activity and stability of Fe2O3@CoFe2O4 were attributed to the synergistic effects of M2+/M3+ (M denotes Co or Fe) redox cycles. SO·-4, ·OH, O·-2 and 1O2 were proved to be the main reactive oxygen species (ROS) involved in the phenol degradation process through quenching experiments and EPR measurements, while the surface-bound SO·-4 played a dominant role. Trace metal ions leached during the reaction enhanced the PMS activation, and the oxygen vacancies electron transfer process played a critical role in the formation of O·-2/1O2 and the cycle of M2+/M3+ redox pairs. The formation of ROS and function of 1O2 were also revealed from bulk reaction and interface reaction. This study highlighted the simultaneous evolution of PMS reduction and oxidation to generate ROS, which provided an insight into the efficient catalytic degradation of persistent organic pollutants (POPs).

Mi, Xueyue;Zhong, Hui;Zhang, Hongxiang;Xu, Shizhe;Li, Yi;Wang, Haitao;Zhan, Sihui;Crittenden, John C. research published 《 Facilitating Redox Cycles of Copper Species by Pollutants in Peroxymonosulfate Activation》, the research content is summarized as follows. The redox behavior of metal active sites determines the rate of heterogeneous catalysis in peroxymonosulfate activation. Previous reports focused on the construction of catalysts for accelerating interfacial electron transfer. In this work, a new strategy was proposed for facilitating valence cycles of Cu⁺/Cu²⁺ by using pollutants. The 2.5Cu/CeO₂/PMS system was capable of achieving the efficient removal of pollutants, including tetracycline, oxytetracycline, and rhodamine B, in a wide pH working range. In the presence of tetracycline, a Cu-N bond was formed between the -NH₂ group of tetracycline and the Cu site of the catalyst, showing that the coordination of Cu active sites changed to CuO₄N₁. The charge of CuO₄N₁ active sites rearranged, making it easier to obtain electrons and promote the PMS oxidation, thereby accelerating the reduction of Cu²⁺ to Cu⁺ and PMS activation. The PMS activation system showed excellent sustainability and selectivity for the removal of organic pollutants. This study provides a novel routine to promote peroxymonosulfate activation by utilizing pollutants to accelerate the redox behavior of metal species.

Li, Xiang;Zhang, Jiajia;Qin, Yang;Zhang, Xingli;Zou, Wei;Ding, Linjie;Zhou, Minghua research published 《 Enhanced removal of organic contaminants by novel iron-carbon and premagnetization: Performance and enhancement mechanism》, the research content is summarized as follows. Iron-carbon (Fe-C) microelectrolysis has attracted considerable attention in wastewater treatment due to its excellent ability to remove contaminants. Herein, novel Fe-C granules were synthesized by simple calcination method for removing organic contaminations, and a cost-effective and environmentally friendly method, namely pre-magnetization, was used to improve the micro-electrolysis performance of Fe-C. Batch experiments proved that premagnetized iron-carbon (pre-Fe-C) could significantly improve the removal of methyl orange (MO) at different Fe-C mass ratios (1:2-2:1), material dosages (1.0-2.5 g/L), initial pH values (3.0-5.0), and MO concentrations (10.0-50.0 mg/L). Electrochem. anal. showed that premagnetization could increase the c.d. and reduce the charge transfer resistance of the microelectrolysis system, making Fe-C more susceptible to electrochem. corrosion. Characterizations confirmed that the corrosion products of the materials included FeO, Fe₂O3, and Fe₃O₄, and more corrosion products were formed in the pre-Fe-C system. Radical quenching experiments and ESR spectroscopy verified that •OH, ¹O₂, and O₂^-• were all involved in pollutant removal, and premagnetization could promote the generation of more reactive oxygen species. Overall, the pre-Fe-C process could effectively remove various organic pollutants, exhibit good adaptability to complex water environments, and hold potential for industrial applications.

A graphitized magnetic biochar material, Fe-impregnated biochar (FBC), was synthesized using biogas residue, a product of food waste after anaerobic fermentation The FBC coupled with ammonium persulfate (APS) exhibited excellent performance in the catalytic degradation of benzo[a]pyrene (BaP), a pentacyclic polycyclic aromatic hydrocarbon (PAH). In the FBC-APS system, the pyrolysis temperature of biochar, the initial pH, and the FBC and APS dosages were all influencing factors for Bap degradation The FBC at the pyrolysis temperature of 700°C performed the best catalytic performance, and FBC-APS efficiently degraded BaP at a wide pH range of 3-11. Results from quenching experiments, ESR measurement, and electrochem. anal. were used as the basis to propose the possible degradation mechanisms of BaP by FBC-APS, including the radical and non-radical pathways. The radical-induced oxidation was attained by SO^·-₄ and O^·-₂. The non-radical pathway involved two aspects, one contributed by ¹O₂ and the other achieved through electron transfer. Five BaP intermediates were tentatively determined Finally, FBC-APS was applied to BaP-polluted soil, and the overall degradation rate reached 91.7% after 72 h. Lettuce growth experiment showed that FBC-APS enhanced soil nitrogen and potassium availability and lettuce growth. In summary, FBC-APS application to soil can degrade BaP, improve the manurial effect, and solve environmental problems brought by biogas residues, i.e., killing three birds with one stone.

In this study, Eu₂O₃/Co₃O₄ nanosheets (NSs) were successfully synthesized and employed to degrade levofloxacin (LVX) via peroxymonosulfate (PMS) activation. Owing to the enhanced transfer efficiency of Co²⁺/Co³⁺ and more adsorbed oxygen, the obtained Eu₂O₃/Co₃O₄ NSs displayed better catalytic performance for PMS activation toward LVX degradation than pure Co₃O₄. The Eu₂O₃/Co₃O₄ NSs can remove 97.93% of LVX only in 6 min via activating PMS, with a reaction rate constant (0.2346 min-1) , which was 2.3 folds of single Co₃O₄ NSs (0.1003 min^-1). Besides, Eu₂O₃/Co₃O₄ exhibited good catalytic performance in presence of different inorganic anions, satisfactory stability and reusability. Singlet oxygen (¹O₂), hydroxyl radical (·OH), sulfate radical (SO₄^·-) and superoxide radical (·O₂^–) contributed to LVX degradation and ¹O₂ played the most key role. In addition, based on the ROSs and LVX degradation intermediates, the possible mechanism and degradation pathways of LVX were further cleared in detail. This work can provide a reference for the eco-friendly and facile preparation strategy of efficient and stable catalysts for rapid and efficient removal of recalcitrant pollutants.
