Abstract
A fiberglass filter element includes: 6 to 12 wt % of zinc oxide-based composite photocatalytic nanoparticles; 3 to 9 wt % of an adhesive system; and 79 to 91 wt % of a superfine fiberglass cotton. The zinc oxide-based composite photocatalytic nanoparticles includes: a rod-like or flower-like zinc oxide photocatalytic nanoparticle (A); a photocatalytic nanoparticle (B), which is one or more selected from graphene, graphene oxide, reduced graphene oxide and graphene quantum dots; a photocatalytic nanoparticle (C), which is one or more selected from a silver nanoparticle and a silver nanowire; and a photocatalytic nanoparticle (D), which is one or more selected from titanium oxide, tin oxide and tungsten oxide.
