▎ 摘  要

NOVELTY - Nanocomposite photocatalytic material comprises spherical titanium dioxide particles comprising graphene coating layer coated on the surface of spherical titanium dioxide. A large number of internally and externally connected pore structures are formed when the spherical titanium dioxide particles are stacked on each other. The spherical titanium dioxide particles are bonded to each other through suspension bond on the surface of the graphene. USE - Used as nanocomposite photocatalytic material. ADVANTAGE - The material has high specific surface area, improved photocatalytic degradation efficiency and increased actual load. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the material, comprising (i) preparing nitric acid solution; (ii) preparing butyl titanate solution; (iii) preparing graphene dispersion; (iv) mixing nitric acid solution and butyl titanate solution to obtain solid colloidal titanium dioxide; (iv) placing the solid colloidal titanium dioxide into oil bath pot, heating, adding graphene dispersion to obtain spherical titanium dioxide particles; and (v) sintering spherical titanium dioxide particles at high temperature to obtain a block structure.
