[0002] Among advanced oxidation technologies, ozone catalytic oxidation is widely used in wastewater treatment due to its advantages of rapid reaction, simple process, and no secondary pollution. However, during the treatment process, the power consumption of generating ozone is high, and the catalyst needs to be replaced regularly, which has high cost. Ozone oxidation catalyst is a selective catalytic material that can change the speed of ozone oxidation reaction. It uses high-quality ceramic, aluminum, carbon, etc. as carriers, and breaks through the method of regulating catalyst structure and performance based on multi-metal co-impregnation and coordination chemistry. It overcomes the problems of low catalytic activity, poor structural stability, and easy detachment of active ingredients of traditional catalysts, and is a hot topic in scientific research.
