NOVELTY - Preparation of nano-black phosphorus/graphene involves mixing phosphorus-tin iodide powder and graphite, tableting to form tablet catalyst, encapsulating with red phosphorus or yellow phosphorus in quartz tube by placing elemental phosphorus source in high temperature zone, and tablet catalyst in low temperature zone separated by porous quartz column in the middle, placing encapsulated quartz tube into two-stage tube furnace for high-temperature treatment, heat preserving, so that phosphorus vapor passes through the catalyst bed to strip the graphite into graphene and form phosphorus/graphene composite and then moving to position of the phosphorus source to obtain nano-black phosphorus/graphene composite material. USE - Preparation of nano-black phosphorus/graphene for energy storage, flame retardance and catalysis applications and used as substrate for preparing composite material. ADVANTAGE - The preparation method is simple, short, efficient and economical, and uses single phosphorus source and graphite as raw material to form strong force between nano-black phosphorus and graphene.
