Further, as shown in fig. 3, in order to further enhance the effect of the ultraviolet catalytic reaction, a plurality of mesh-like zinc oxide coatings 714 are uniformly arranged on the surface of the titanium dioxide mesh at intervals. The principle of titanium dioxide and zinc oxide as photocatalysts is that electron-hole pairs are generated to participate in various chemical reactions, but the two are different in the light absorption range, the electron transition speed and the like, and the titanium dioxide and the zinc oxide are combined for use, so that the advantages of the two can be fully exerted, a synergistic effect is generated, and the catalytic effect is improved.
