Abstract

A glass fiber filter element for visible light photocatalysis and air purification and a method for preparing the same. The glass fiber filter element includes 4 to 7 wt % of nanoparticles including at least one selected from zinc oxide, graphene oxide, titanium oxide, and reduced graphene oxide, 2 to 7 wt % of silver nanowires, 3 to 12 wt % of an adhesive system, and 78 to 91 wt % of a glass fiber mat, based on the total weight of the glass fiber filter element. The glass fiber mat is made of at least two glass fibers with different diameters, and the diameters are in a range of 0.15 to 3.5 μm. The nanoparticles have a particle size from 1 to 200 nm, and the silver nanowires have a diameter of 15 to 50 nm.
