▎ 摘　　要

NOVELTY - Preparing powder shaped complex photo-catalytic material comprises preparing net-shaped nano complex photo-catalytic material comprising a foamed metal with a porous structure, growing a number of graphene on the foamed metal and a metal oxide catalytic material on the graphene, growing a number of graphene on a porous metal foam, to form a three-dimensional structure of the cell wall surface and shaking the net-shaped nano complex photo-catalytic material, to obtain a graphene-metal oxide catalytic material which is released from the mesh-like nano complex photocatalytic material. USE - The method is useful for preparing powder shaped complex photo-catalytic material (claimed). ADVANTAGE - The method: can improve the photo-catalytic activity and practical value of the photocatalytic material.
