▎ 摘　　要

NOVELTY - Graphene quantum dot doped titanium dioxide catalytic electrode preparation involves dispersing graphene quantum dot in an aqueous solution uniformly containing a surfactant to synthesize graphene quantum dot core as a template. The surfactant is a liquid crystal. The obtained graphene quantum dot core is mixed with titanium tetrachloride, water, and hydrochloric acid to prepare a liquid crystal-inorganic precursor solution. The prepared liquid crystal-inorganic precursor solution is applied on conductive glass by spraying techniques for receiving conductive glass-inorganic precursor. USE - Method for preparing graphene quantum dot doped titanium dioxide catalytic electrode (claimed). ADVANTAGE - The method prepares graphene quantum dot doped titanium dioxide catalytic electrode with efficient gas diffusion, electrical conductivity, and uniform diameter distribution in a simple manner on industrial scale. DETAILED DESCRIPTION - Graphene quantum dot doped titanium dioxide catalytic electrode preparation involves dispersing graphene quantum dot in an aqueous solution uniformly containing a surfactant to synthesize graphene quantum dot core as a template. The surfactant is a liquid crystal. The obtained graphene quantum dot core is mixed with titanium tetrachloride, water, and hydrochloric acid to prepare a liquid crystal-inorganic precursor solution. The prepared liquid crystal-inorganic precursor solution is applied on conductive glass by spraying techniques for receiving conductive glass-inorganic precursor. The received conductive glass-inorganic precursor is treated with extraction agent for removing template, and then treated at low temperature to form graphene graphene quantum dot doped titanium dioxide catalytic electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic transmission electron microscopic image of the prepared graphene quantum dot doped titanium dioxide catalytic electrode.
