AI Technical Summary

Problems solved by technology

Most of the existing photocatalytic reactors use ultraviolet lamps as the direct light source, and direct contact between electricity and heat and the working environment is inevitable. It is mainly aimed at indoor air and cannot be used in closed, flammable and explosive environments such as airplanes, subways, trains, and factories. environment, and cannot solve the problems of low catalytic efficiency and secondary pollution in the photocatalytic process
