▎ 摘　　要

NOVELTY - Photocatalyst composition comprises 60-70 wt.% titanium dioxide, 15-20 wt.% graphene and 15-20 wt.% photoconductive materials (200). USE - The composition is useful in the air filtration structure (claimed). ADVANTAGE - The composition improves the air purification ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an air filtration structure comprising the photocatalyst composition and a substrate (300), where the particle sizes of titanium dioxide is below 10 nm, and the photoconductive materials irradiate UV or blue light to titanium dioxide to improve air purification effect. DESCRIPTION OF DRAWING(S) - The figure shows a schematic diagrammatic of the air filtration structure. Compounds (100) Photoconductive materials (200) Substrate (300)
