▎ 摘　　要

NOVELTY - Preparation of nano photocatalytic material comprises preparing bismuth tungstate; preparing reduced graphene oxide through graphene oxide; preparing graphitic carbon nitride-bismuth tungstate through graphitic carbon nitride and bismuth tungstate; and preparing reduced graphene oxide-graphitic carbon nitride-bismuth tungstate. USE - The method is used for preparation of nano photocatalytic material. ADVANTAGE - The material enhances separation and transport capabilities of photogenerated electron-hole pairs and has improved redox ability and photocatalytic activity.
