Abstract ：
Interfacial engineering, which efficiently modulates the electron density and optimizes the electronic structure, has rapidly emerged as a promising strategy to facilitate Fenton-like reaction processes. Here, an interfacial catalyst with Fe7S8 coupled tubular g-C3N4 (TCN) was crafted for peroxymonosulfate (PMS) activation. Density functional theory (DFT) calculations revealed that the introduction of TCN in the interfacial engineering facilitated the d-band center of Fe7S8 to be closer to the Fermi energy level, enlarged the contribution of Fe-3d orbitals and raised the number of conductive carriers, resulting in higher PMS activation ability and electron utilization efficiency. S species promote valence cycling of Fe and improve catalytic efficiency as well. 5 mg & sdot;L- 1 tetracycline (TC) was efficiently eliminated with a high rate (0.49 min- 1) under dark conditions at 25 degrees C in 10 min. Moreover, contaminants containing electron-donating groups were susceptible to effective degradation. Given DFT calculations and experiments, the intermediate (*O) was the key precursor for the generation of 1O2, determining the reaction rate, while electron transfer process (ETP) was proposed. This work sheds new insights for interfacial engineering to manipulate the electronic structure of catalysts and enhanced catalytic performance, facilitating practical ecological remediation.

Abstract ：
A novel bimetallic heterojunction catalyst (Co2Mo3O8/Co9S8) with hydrangea-like structure was prepared by a straightforward one-pot hydrothermal and pyrolysis method, which was then applied for the efficient activation of peroxymonosulfate (PMS) in wastewater purification. Density functional theory (DFT) simulations revealed that the formation of the Co2Mo3O8/Co9S8 heterojunction increased the adsorption energy of PMS and elongated the O-O bond within PMS. Moreover, an internal electric field generated within the heterojunction further activated PMS through electron-deficient centers, establishing a degradation mechanism primarily dominated by non-radical pathways. Meanwhile, the exist Co(II) and Mo(IV) involved as active sites for enhanced catalytic performance through the redox cycling of metal valence states. In the optimized Co2Mo3O8/Co9S8-PMS system, the target pollutant doxycycline (DOX) was rapidly and efficiently degraded, with a relatively low activation energy (3.93 kJ & sdot;mol- 1). Furthermore, the system demonstrated strong adaptability to interference from inorganic anions, humic acid, and pH variations, while effectively removing various pollutants. It consistently maintained a relatively high DOX removal efficiency in cyclic experiments and continuous flow reaction experiments. The present study provided new insights for improving the rational design of bimetallic heterojunction catalysts, and contributed to a more effective and sustainable solution for environmental remediation.

Abstract ：
The pervasive presence of antibiotics in the environment poses ecological risks and jeopardizes human health. Herein, a simple one-step hydrothermal method was used to prepare a boron-doped (B-doped) bimetallic carbon felt as a cathode for the heterogeneous electro-Fenton (HEF) system. In the HEF process, the modified electrode (B-Co/Fe@CF) demonstrated exceptional efficiency in degrading the target pollutant doxycycline (DOX), owing to its maximal degree of defect and minimal electrochemical impedance. In addition, XPS and structure-activity relationship analysis results revealed that the superior performance of the modified electrode stemmed from the predominant influence of sp(3)/sp(2), C=O and metal-boron (M-B) groups in initiating the production of H2O2 and the consequent formation of reactive oxygen species (ROS). Meanwhile, the introduction of non-metallic boron species significantly accelerated the sustainable cycling of Co(II)/Co(III) and Fe(II)/Fe(III). The quenching and probe experiments suggested that the radicals center dot O-2(-) and center dot OH significantly contributed to the elimination of DOX. Moreover, the advanced B-Co/Fe@CF-HEF system exhibited remarkable versatility, stability and effectiveness throughout the degradation process. Three pathways for the degradation of the pollutants were identified using density functional theory (DFT) calculations and LC-MS detection. Additionally, the treated DOX solution significantly reduced the toxicity to the growth of E. coli and mung bean in actual toxicity experiments. This research presented a novel outlook on developing the B-doped metal catalysts for efficient degradation of pollutants and showcased promising applications in organic wastewater treatment.

Abstract ：
Peracetic acid (PAA) as emerging oxidant in advanced oxidation processes (AOPs) has attracted widespread attention in purifying water pollution. In this research, the removal of target contaminant (sulfamethoxazole, SMX) was investigated through PAA activation by a facile catalyst (Co@C), and the active sites of catalyst were identified as sp(3)-C, O-ads, and Co-0 by correlation analysis. Especially, different pH adjustment strategies were designed, including System A (adjusting pH after adding PAA) and System B (adjusting pH before adding PAA), to investigate the impact of oxidant acidity and alkalinity on solution microenvironment as well as effect and mechanism of pollutant removal. The results showed that HO and CH3C(O)OO dominated in System A, while Co(IV)O2+ was also observed in System B. Both systems showed optimal SMX degradation (98 %). However, System A exhibited excellent water quality tolerance (efficiency > 78 %), superior sustained catalyst activation (efficiency > 80 % in 40 h), less ion leaching (41 mu g L-1), and lower products toxicity. Moreover, the pH of solution after reaction in System B was intensely acidic, requiring costly pH adjustments for discharge. This study unveils the strategy of adjusting pH after adding PAA is preferable for water purification, enriching the emerging research of PAA-based AOPs for the remediation of environments.

Abstract ：
In recent years, metal-free catalysts for persulfate-mediated oxidation processes have been widely applied to remove contaminants in the aquatic environment. Herein, a simple pyrolysis approach was used to synthesize the boron doped biochars (B@TBCs) derived from boric acid mixed with tea seed shells powders. The obtained B@TBCs exhibited fantastic capability to boost PMS (0.5 mM) activation for 90%~ removal of oxytetracycline (OTC) within 20 min. Through the correlation analysis and DFT calculations, it was concluded that the apparent rate constant of pollutants removal was greatly related to the-O-B -O-groups on the biochars, which could improve the electron-donating capacity of the biochar. In addition, the degradation process of OTC was pH -dependent because of the changed roles of ROSs under different pH. Finally, according to the DFT calcula-tion, LC-MS and toxicological analysis, the degradation pathways of pollutants and the toxicity changes during the degradation process were obtained. These findings consolidated the theoretical basis for further boosting the catalytic activity of B-doped biochars and expanded the imagination for the modification of other metal-free biochar catalysts for PMS activation.

Abstract ：
Recently, atomically dispersed dual-metal sites carbocatalysts (DMSCs) make a wave in the field of persulfate-based advanced oxidation processes (PS-AOPs) in light of their approximate to 100% atomic utilization efficiency, high density of active sites, and superior catalytic activity. This review aims to provide a state-of-the-art overview on the development of DMSCs for activating PS. Initially, the types and properties of DMSCs are summarized, as well as the role of doping different heteroatoms is discussed. Subsequently, the properties of different carbon carriers and the methods for the synthesis of DMSCs are outlined. After that, the mechanism and application of DMSCs for the activation of PS toward organic contaminants degradation are revealed. Particularly, the mechanism of nonradical pathway is described, and the necessity of coupling DMSCs-based PS-AOPs to other processes for practical water treatment is emphasized. Finally, the formidable challenges and future research directions of DMSCs are proposed. This review is expected to provide insight into the preparation of DMSCs in the field of nanomaterials and to broaden the path for their environmental applications.

Abstract ：
There has been extensive research on biochar materials in the field of adsorption, catalysis, etc. Hereon, we reported a gentle synthesis of electrode by abundant biomass of municipal sludge and cheap precursor of boric acid as carbon source and boron source. Experimental results demonstrated that a small amount of boron doping had a profound impact on the elemental composition and active sites of sludge-based biochar significantly, resulting the improvement of EF activity for sulfamerazine (SMR) removal. Under the optimal reaction conditions, including initial pH, added divalent iron, applied current and air flow, 95.12% of SMR could be removed in 180 min in EF system. It was confirmed that hydroxyl radical (center dot OH) and superoxide radical (center dot O-2(-)) were the primary active substances for SMR degradation. The effect experiments of various ions, types of wastewater and pollutants were carried out and the stability experiments were conducted for eight cycles without significant efficiency loss, which proved the exceptional applicability and reusability of the gained boron doped sludge-based biochar electrode BSBC-E. These functions of boron-doped sludge-based biochar cathode could be a promising material for emerging organic contaminants remediation.

Abstract ：
Metal sulfides have been found to be effective in removing organic pollutants from water in environmental catalysis. In this study, a porous graphitic biochar wrapped Co9S8 core-shell composite (Co9S8@N-O-BC) was designed for efficient activation of peroxymonosulfate (PMS) and degradation of sulfamethoxazole in an aqueous environment. Based on complementary characterizations and reactive oxygen species (ROS) quenching experiments, we proposed that boosted Co(ii) regeneration by various existing S species along with formed N and O active sites in Co9S8@N-O-BC facilitated the cleavage of the O-O bond of PMS, thus resulting in a high-efficiency non-radical pathway. Consequently, Co9S8@N-O-BC/PMS achieved an outstanding degradation of sulfamethoxazole (100%) within 4 min in a wide pH range (3-11) and its turnover frequency (TOF) value was 11.96 min(-1), up to 117 times higher than other reported catalysts as far as we know. The superior stability and wide applicability in sulfamethoxazole degradation with a series of inorganic ions, especially the production of very few harmless intermediates and the exceptional mineralization efficiency, also further demonstrated that the obtained catalyst possessed excellent potential for practical wastewater treatment.

Abstract ：
Electro-Fenton is one of the promising clean and renewable technologies for refractory pollutants control. Herein, a ternary metal-layered double hydroxide (CoFeCe-LDH) nanoparticle in situ growth on carbon felt (CF) was prepared to fabricate heterogeneous electro-Fenton (HEF) cathode via one-pot hydrothermal strategy. The optimal CoFeCe-LDH@CF cathode demonstrated high oxygen reduction activity, low resistance and efficient degradation of DOX over a wide pH range (pH = 1-9). On one hand, the introduction of Ce resulted in the generation of plenty of oxygen vacancies (O-alpha) on the electrode surface. On the other hand, the coexistence of Co2+/Co3+, Fe2+/Fe3+ and Ce3+/Ce4+ redox pairs significantly enhanced interfacial electron transfer and promoted the generation and decomposition of in situ H2O2, which in turn boosted the production of reactive radicals ((OH)-O-center dot, O-2(center dot-) and O-1(2)). The Estimation Program Interface (EPI) certificated that intermediates resulted from DOX degradation in the system were relatively low in toxicity to typical aquatic organisms. Meanwhile, the effect experiments of various ions, types of wastewater and pollutants were carried out in the CoFeCe-LDH@CFs-HEF system and all showed excellent pollutant degradation, proving that the developed cathode had special applicability and reusability. Thus, this paper gave a global contribution to develop the high-performance cathode by exploring the synergistic effects of trimetals in LDH and proposed a reliable strategy for enhanced degradation of contaminant by HEF system.
