▎ 摘　　要

NOVELTY - Graphene/fullerene/graphitic carbon nitride heterojunction composite film photocatalytic material is obtained by immersing glass plate in polyethyleneimine, soaking glass plate in deionized water, drying, immersing glass plate in graphene, washing and drying, immersing glass plate in polyallylamine hydrochloride, immersing glass plate in C60 fullerene, washing and drying, immersing glass plate in polypropylene hydrochloride, immersing glass plate in graphitic carbon nitride, washing and drying, repeating process to form multilayer film and peeling resulting film from glass plate. USE - Graphene/fullerene/graphitic carbon nitride heterojunction composite film photocatalytic material is used for producing hydrogen by photolyzing water under radiation of visible light (claimed). ADVANTAGE - The graphene/fullerene/graphitic carbon nitride heterojunction composite film photocatalytic material has excellent catalytic activity even at wavelength of 400-800 nm. DETAILED DESCRIPTION - Graphene/fullerene/graphitic carbon nitride heterojunction composite film photocatalytic material is obtained by immersing glass plate in an aqueous solution of certain concentration of polyethyleneimine for 15 minutes, soaking the glass plate in deionized water for 1 minute, drying in a nitrogen stream, immersing the glass plate in a certain concentration of aqueous solution graphene for 15 minutes, washing and drying, immersing glass plate in a concentration of polyallylamine hydrochloride for 15 minutes, washing and drying, immersing glass plate in an aqueous solution of a certain concentration of 60C fullerene for 15 minutes, washing and drying, immersing the glass plate in polypropylene hydrochloride for 15 minutes, washing and drying, immersing the glass plate in a certain concentration of graphitic carbon nitride for 15 minutes, washing and drying, repeating the process to form a multilayer film (polyethyleneimine/graphene/polyallylamine hydrochloride/60C fullerene /polypropylene hydrochloride/graphitic carbon nitride), and peeling the resulting film from glass plate for photocatalytic reaction.
