Abstract ：
The advanced oxidation process using cobalt-based composites to activate peroxymonosulfate (PMS) for the degradation of organic pollutants has attracted significant research interest. However, cobalt-based catalysts face challenges such as limited cycling of Co(III)/Co(II) and poor stability. This study introduces a new biocharsupported bimetallic Co/Mo composite (Co/CoMoO3@WBC), where wheat bran serves as the carrier. This composite effectively activates PMS to degrade ciprofloxacin (CIP), achieving a 99 % removal efficiency within 30 min. X-ray photoelectron spectroscopy measurements showed that low-valence Mo(IV) can reduce Co(III) to Co(II) and transform into Mo(VI). Co/CoMoO3@WBC demonstrated outstanding cycling performance, maintaining a CIP removal efficiency of 89 % after five consecutive tests. Quenching and electron paramagnetic resonance experiments revealed that SO4 center dot- and O-2(center dot-) were the main reactive oxygen species in the system. In addition, the incorporation of Mo reduced the leaching of metal ions. The Co ion leaching after five cycles of Co/ CoMoO3@WBC catalysis (0.292 mg/L) was considerably lower than that of the wheat bran-supported singlemetal Co catalyst (0.842 mg/L). This work introduces a new method for utilizing wheat bran and provides a promising strategy for enhancing Co valence cycling and reducing Co leaching in Co-based catalysts.

Abstract ：
To address the issue of insufficient oxygen activation by electrode materials in electro-Fenton-like technology, we prepared a novel composite by one-step electrodeposition on graphite felt (GF) followed by calcination. The CuO@Co3O4/GF composite possessed oxygen vacancies and a heterostructure, which effectively modulated the catalyst's charge distribution, facilitating oxygen adsorption and activation. The heterostructure enhanced the interfacial electron transfer between CuO and Co3O4, shifting the Co d-band center to higher energies and increasing its electron density, which reduced the oxygen adsorption energy barrier. The presence of oxygen vacancies reduced the kinetic barriers of the oxygen reduction reaction and provided additional active sites. CuO@Co3O4/GF was utilized for chloroquine phosphate degradation, achieving 100 % removal within 60 min, with a reaction rate 5.6 times higher than that of GF, and exhibited exceptional stability and applicability over a broad pH range. This study presents a facile approach for preparing composites with both oxygen vacancies and heterostructures, providing new insights into enhancing electrocatalytic performance.

Abstract ：
The leaching of toxic metals is still problematic for heterogeneous metal catalysts in activating peracetic acid (PAA). Herein, CoFe/U-ZrO2 was synthesized by loading CoFe onto the metal-organic framework (UiO-66) derived ZrO2 (U-ZrO2) for PAA activation. The high porosity and specific surface area of UiO-66 enable efficient embedding and uniform dispersion of CoFe particles into pore channels. The supported material effectively activates PAA and significantly reduces Co leaching. CoFe/U-ZrO2-PAA system shows a removal efficiency of sulfamethoxazole reaching 98.9% within 10 min with Co leaching concentrations as low as 0.005 mg/L (equivalent to 1.4% of CoFe-PAA system). Quenching experiments, probe experiments and electron paramagnetic resonance tests identify CH3C(O)OO center dot as the dominant radical species. The CoFe/U-ZrO2-PAA system maintains high activity in actual water bodies and can resist the interference of HPO42-, Cl-, SO42-, NO3-and humic acid except for the inhibitory effect of HCO3- . The system also displays good stability and high degradability to different pollutants, maintaining consistently outstanding degradation efficiency in the flow-through experiment. Overall, the environmentally friendly, good efficiency, and high stability of the CoFe/U-ZrO2-PAA system makes it potential for broad applications in wastewater treatment.

Abstract ：
Herein, we fabricated a novel NiO@CuxO nanorods (NRs) composite electrode grown in-situ on copper foam (CF), designated as NiO@CuxO NRs/CF. This electrode demonstrates excellent performance in a heterogeneous electro-Fenton-like system. It efficiently activates O2 to generate 1O2 in-situ without the addition of oxidant precursors and effectively degrades chloroquine phosphate (CQ). The combination of NiO and CuxO nanoarrays created multiple synergistic sites for molecular oxygen adsorption and activation. The addition of NiO induced the formation of low-valence Cu species and effectively optimized oxygen reduction reaction (ORR) kinetics. This enhancement led to an increased generation of key intermediates (center dot O2- and center dot OH), which further promoted the efficient production of 1O2 through the chain reaction mediated by center dot O2- and center dot OH. NiO@CuxO NRs/CF achieved a 3.9-fold increase in 1O2 production compared to the CF electrode. NiO@CuxO NRs/CF electrodes exhibited exceptional performance in degrading CQ across a wide pH range (3-11). Meanwhile, it also displayed remarkable stability and anti-interference capability, highlighting their promising potential for practical applications. The study provides an innovative strategy for the in-situ production of 1O2 through molecular oxygen activation with a bimetallic composite catalyst to efficiently degrade organic pollutants.

Abstract ：
The efficient degradation of antibiotics holds significant implications for mitigating environmental pollution. This study synthesized a montmorillonite chitosan composite material (MMT-CS) using the gel template method. Subsequently, a bio-enhanced reactor was constructed to facilitate the degradation of chlorotetracycline (CTC). The addition of MMT-CS composite material enables the degradation of different concentrations of CTC. MMTCS, a conductive carrier, effectively promotes microbial adhesion and boosts the metabolic activity of functional microorganisms. Additionally, it facilitates the maintenance of microbial activity under CTC pressure by promoting the secretion of extracellular polymeric substances, increasing critical enzyme activity, and enhancing the electron transfer capacity within the system. In this MMT-CS bio-enhanced process, Paracoccus (11.4%) and Bacillus (3.9%) are utilized as essential bacteria genes. The results of metabolic pathways prediction indicated significant enhancements in membrane-transport, nucleotide-metabolism, replication-repair, and lipidmetabolism. Thus, the developed self-supporting MMT-CS bio-enhanced process ensured the stability of the system during the removal of antibiotics.

Abstract ：
Chloroquine phosphate (CQP), commonly used in treating autoimmune diseases and malaria, has been detected in various water bodies and poses potential hazards to the ecological environment. In this study, ZIF-67-derived Co 3 S 4 -modified graphite felt cathode (Co 3 S 4 /GF) was used to construct a heterogeneous electro-Fenton system for efficient CQP removal. The introduction of sulfur greatly improved the electron transfer rate and reduced the charge transfer resistance, garnering the Co 3 S 4 /GF composite cathode with excellent electrochemical activity. The Co 3 S 4 /GF electro-Fenton system completely removed CQP within 60 min at near -neutral initial pH and exhibited 19.3 % higher CQP removal efficiency than the ZIF-67/GF system. This enhanced performance was mainly attributed to the introduction of sulfur, which increased the proportion of low-valent metal in the material and promoted the Co III and Co II cycle. The hydroxyl radical was identified as the main radical involved in CQP degradation. The intermediates of CQP degradation were detected, and four possible degradation pathways of CQP were obtained. The ecotoxicity of CQP and its intermediates decreased during the degradation process. This work proposes novel ideas for the rapid development of metal -organic framework -derived Co/S-based materials for their application in the field of environmental catalysis.

Abstract ：
Excess sludge fermentation is a commonly employed method for carbon sources in wastewater treatment plants, but its use as a carbon source for chlorophenol removal has been relatively underexplored. In this study, a laboratory-scale sludge fermentation SBR (FSBR) was integrated with a 2,4,6-trichlorophenol (2,4,6-TCP) degradation SBR (DSBR), resulting in a stable removal of 2,4,6-TCP without the need for external carbon sources. In this coupled system, the concentrations of volatile fatty acids in FSBR remained constant, with acetic acid, propionic acid, butyric acid, and valeric acid concentrations reaching 322.04 mg COD/L, 225.98 mg COD/L, 274.76 mg COD/L, and 149.58 mg COD/L, respectively, and the acid production efficiency increased to 88.40%. Throughout the 110-day operational period, the activated sludge concentration in the DSBR was consistently maintained at 3021 +/- 110 mg/L, and the sludge SVI remained stable at 70 mL/g. The maximum amount of 2,4,6-TCP removed reached 240.13 mg/L within a 12 h operating cycle. The use of excess sludge fermentation can completely replace commercial carbon sources for 2,4,6-TCP removal, leading to cost savings in chlorophenol treatment and broadening the applicability of this technology.
