Summary: In this study, a modified Bi-PbO2 electrode was used to simultaneously degrade fenitrothion, trifluralin, and chlorothalonil in synthetic and pesticide wastewater. A high-performance liquid chromatography method was developed to identify the pesticides simultaneously. Quadratic models were developed to investigate the effects of operating parameters and predict the degradation efficiencies. The maximum degradation efficiencies obtained were 99.7%, 100%, and 100% for fenitrothion, trifluralin, and chlorothalonil, respectively.

Summary: This study investigated the enhanced mechanism of electrochemical degradation of antibiotic norfloxacin using a self-made Ti/SnO2-Sb2O3/alpha,beta-Co-PbO2 electrode. The Co-doped PbO2 electrode exhibited improved characteristics for the electrochemical oxidation of NOR, achieving high removal rates of NOR, COD, and TOC under optimal operating parameters. Through the detection of intermediates, a reaction pathway involving decarboxylation, defluorination, and piperazine ring-opening was proposed. The toxicity assessment results showed that electrochemical oxidation effectively reduced the toxicity of NOR to the environmental ecosystem.

Summary: In this study, small amounts of bismuth and cerium were co-doped in the titanium matrix lead dioxide anode using the electro-deposition method. The Ti/PbO2/Bi-Ce 03 electrode showed the best catalytic effect and surface structure. Doping improved the corrosion potential, accelerated lifetime, degradation efficiency, and reduced the electrochemical impedance of the electrode. The degradation of DOX on Ti/PbO2/Bi-Ce 03 electrode was mainly attributed to direct oxidation and SO4-.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
