Electrospinning and hydrothermal techniques were utilized to synthesize and fabricate high-efficiency visible-light-responsive fibrous filter membrane heterojunction photocatalysts. The impacts of the size, morphology and structure of photocatalytic materials on their photocatalytic performance were studied. By regulating preparation process parameters and crystal growth, the utilization efficiency of photogenerated charge carriers was improved, and the solar light utilization range of the photocatalysts was broadened. A novel high-efficiency flow-through membrane filtration photocatalytic reactor was developed, which exhibits excellent oxidative degradation effects on common pollutants in printing and dyeing wastewater. Through research on the mass transfer process at the chemical reaction interface, a coupled kinetic model of mass transfer diffusion and oxidation reaction was established. The activation energy and pre-exponential factor of the reaction were determined, the variation rules of activation energy and pre-exponential factor were investigated, as well as the relationship between solution chemical parameters and the removal rate of organic pollutants.
