Claim 10:
11. A method for preparing the glass fiber filter element for visible light photocatalysis and air purification according to claim 1, comprising:
(1) selecting two or more glass fiber mats with different glass fiber diameters, putting the glass fiber mats into a mixed liquid containing nanoparticles and silver nanowires, and using a fiber dissociator for stirring the mixed liquid to obtain a slurry;
(2) transporting the slurry to a paper machine for wet forming to obtain a wet paper with a seed layer of the nanoparticles, immersing the wet paper in an adhesive system, and drying the wet paper to obtain a glass fiber paper;
(3) immersing the glass fiber paper in a solution comprising the nanoparticles or precursors thereof, and drying the glass fiber paper;
(4) performing an annealing process on the glass fiber paper to obtain a filter paper; and
(5) folding the filter paper in a zigzag shape to obtain the glass fiber filter element.
