▎ 摘  要

NOVELTY - Preparing novel photocatalyst composite sterilization material comprises placing bismuth metal in vacuum furnace and heating to predetermined temperature, adding excess graphene powder to the vacuum furnace and maintaining the predetermined temperature for predetermined time, obtaining mixed product, where the mixed product comprises bismuth carbide and graphene powder, adding the mixed product to the molten plastic material and mixing to obtain composite slurry, and drawing and cutting the composite slurry into particles to prepare the novel photocatalyst composite sterilization material. USE - The sterilizing material is useful for preparing food packaging bags (claimed). ADVANTAGE - The sterilization material: can sterilize; has the function of removing formaldehyde in the air; is healthy sterilization and environmental protection material; and has wide market application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for novel photocatalyst composite sterilization material prepared by the preparation method.
