NOVELTY - Graphite-type carbonitride is ultrasonically dispersed in 1,3-butanediol and the obtained suspension is centrifuged. The obtained solid is dried to obtain a graphene-carbonitride photocatalytic material. USE - Preparation of graphene-carbonitride photocatalytic material (claimed). ADVANTAGE - The method enables simple, economical and environmentally-friendly mass-production of graphene-carbonitride photocatalytic material having excellent photocatalytic performance characteristics, photocurrent response, and adsorption capacity, under mild reaction conditions. The solvent used can be recycled.
