[0004] At present, the research on the catalytic efficiency of photocatalytic materials has become one of the hotspots in the field of photocatalytic research. For solid powder catalysts, they are in sufficient contact with the solution, but it is difficult to separate them; the contact area between bulk or membrane catalytic materials and liquid is small, and the catalytic efficiency is low; In order to improve the catalytic efficiency of the photocatalyst, it is possible to increase the contact area, increase the flow rate of the liquid, or use ultrasonic waves, etc., but the above methods have a high cost for the preparation of the catalyst and the energy consumption of the auxiliary means of the catalytic process, and the implementation process is relatively complicated.
