▎ 摘　　要

NOVELTY - The invention relates provides a photocatalyst composite material comprising titanium dioxide and graphene. The invention also provides a method for manufacturing photocatalystic composite nano fiber. The method comprises mixing a titanium precursor, an organic molecule and an organic solvent to form an initial solution, heating the initial solution and mixing with graphene to form an electrospinning solution, and forming multiple nano fibers from the electrospinning solution through electrostatic spin. The invented photocatalystic composite material can effectively absorb visible lights to quickly decompose organic pollutants.
