Abstract
Provided is a fabrication method of a photocatalytic material in which a single layer of a carbon-based participate is formed on a surface of each of titanium dioxide particle. The method includes (a) loading titanium dioxide particles into an electric furnace comprising a mechanism for rotating a core tube; (b) heating an inside of the core tube of the electric furnace into which the titanium dioxide particles have been loaded to a temperature of not less than 400° C. and not more than 800° C., while an inert gas is introduced into the inside of the core tube; (c) supplying a hydrocarbon gas to the inside of the core tube in addition to the inert gas; and (d) performing a thermal CVD on each of the titanium dioxide particles in a fluidized state inside the core tube, while the core tube is rotated, to form a single layer of a carbon-based precipitate containing graphene on a surface of each of the titanium dioxide particles. A photocatalyst material is provided.
