This technology has the advantages of fast deposition rate, good coating uniformity, and can be used to prepare various functional materials.In this study, a nickel-based nanotitanium dioxide composite plating was prepared by high-frequency pulse electrodeposition, and its photocatalytic performance for the degradation of wastewater pollutants was studied. The microstructure, structure, and light absorption performance of the coating were studied by SEM, XRD, UV-Vis, etc., and the efficiency of the composite coating for the degradation of wastewater pollutants was tested using a photocatalytic reactor. The reaction mechanism was also discussed.This study can provide certain reference significance for the application of high-frequency pulse electrodeposition technology in the field of functional material preparation and provide a new idea for the development of photocatalytic wastewater treatment technology.Keywords: high-frequency pulse electrodeposition; nanotitanium dioxide; composite coating; photocatalysis; wastewater treatment
