▎ 摘  要

NOVELTY - Preparation of black phosphorus alkene-graphene composite material hollow microsphere comprises adding black phosphorus alkenyl nanosheet or black phosphorus alkenyl quantum dot dispersion solution into graphene nanosheet dispersion, and mechanically stirring to obtain mixed oxide dispersion; spraying into liquid helium, rapidly freezing into composite microspheres, and freeze-drying to obtain composite hollow microspheres; and subjecting to high-temperature reduction reaction under nitrogen or argon atmosphere to reduce graphene oxide to graphene. USE - Method for preparation of black phosphorus alkene-graphene composite material hollow microsphere (claimed) used for lithium ion batteries, supercapacitors, sensors and filtration purification.
