Focusing on the goal of high-efficiency and low-consumption treatment, this project intends to conduct in-depth research on innovative anode materials and process coupling, using the characteristics of porous TiO2 nanotubes with large specific surface area, strong mass transfer and many active sites, and using boron and cobalt co-doping to improve the catalytic performance and stability of TiO2 nanotubes, which was used to construct a filter-type high-efficiency porous anode-coupled cathode-activated persulfate system. The focus is on (1) the mechanism of boron and cobalt elements improving the catalytic performance and stability of porous TiO2 nanotube electrodes, and the development a porous anodes with high oxygen evolution potential, good catalytic activity and stability; (2) revealing the strengthens mechanism and process of organophosphorus pesticide removal at filter-type porous anode coupled cathode activated persulfate; (3) Exploring the key operating parameters of the filter coupling system to treat organophosphorus pesticides and the coupling system's effectiveness, adaptability and electrode stability for the degradation of wastewater containing organic phosphorus. This has important academic significance and application prospects for expanding the preparation and environmental application of porous TiO2 nanotube electrodes, promoting the application of filter-type porous anode electrochemical coupling technology, and developing new technologies for high-efficiency and low-consumption treatment of organophosphorus pesticides.
