▎ 摘　　要

NOVELTY - Preparing antibacterial photocatalytic oxychloride/graphene two-dimensional heterojunction comprises (i) adding graphene and polyvinylpyrrolidone to deionized water and mixing uniformly to obtain a graphene suspension, (ii) dissolving mannitol and bismuth nitrate pentahydrate in deionized water to obtain a bismuth nitrate pentahydrate solution, adding the graphene suspension, mixing uniformly, then adding sodium chloride, then hydrothermally reacting and stopping the reaction, washing and drying. USE - The antibacterial photocatalytic oxychloride/graphene two-dimensional heterojunction is useful in the field of photocatalytic-antibacterial (claimed). ADVANTAGE - The method: is convenient, economical and environmentally friendly; has no toxicity and easy process; and the obtained product can quickly kill the bacteria under the irradiation of xenon lamp. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for antibacterial photocatalytic oxychloride/grapheme two-dimensional heterojunction prepared by the above mentioned method.
