▎ 摘　　要

NOVELTY - Graphitic carbon nitride based composite photocatalytic material comprises graphitic carbon nitride, hematite and reduced graphene oxide (RGO), where hematite is dispersed on the surface of graphitic carbon nitride and RGO is interposed between the hematite and graphitic carbon nitride. USE - Used as graphitic carbon nitride based composite photocatalytic material. ADVANTAGE - The composite photocatalytic material has wide photo-response range, high degradation efficiency to organic dye RhB, excellent photocatalytic performance. The method has simple operation procedure and less equipment use; is economical and environmentally-friendly; and can achieve large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite photocatalytic material, comprising mixing graphitic carbon nitride and hematite by stirring to obtain a suspension of graphitic carbon nitride/hematite binary complex, uniformly dispersing graphene oxide in the suspension and reducing graphene oxide to RGO.
