▎ 摘　　要

NOVELTY - Nanocomposite photocatalytic material comprises a block structure formed by stacking multiple spherical titanium dioxide particles coated with graphene. The block structure is a multiple inner and outer connected hole structures formed between the spherical titanium dioxide particles coated with graphene on the surface. The spherical titanium dioxide particles coated with graphene on the surface include an inner spherical titanium dioxide and an outer graphene coating layer. The spherical titanium dioxide particles coated with graphene on the surface are bonded to each other through dangling bonds on the surface of the graphene. USE - Used as nanocomposite photocatalytic material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing nanocomposite photocatalytic material comprising preparing a nitric acid solution, preparing a butyl titanate solution, preparing a graphene dispersion, preparing a colloidal titanium dioxide solid, preparing graphene-coated spherical titanium dioxide particles by heating in an oil bath, sintering at high temperature, and stacking the spherical titanium dioxide coated with graphene on top of each other to form a bulk structure.
