▎ 摘　　要

NOVELTY - Titanium dioxide/reduced graphene oxide (RGO) composite material comprises two-dimensional (2D) layered titanium dioxide and 2D layered reduced graphene oxide. The two-dimensional layered titanium dioxide and two-dimensional layered reduced graphene oxide are combined with each other through intermolecular forces. USE - The catalyst is useful for catalyzing reduction of oxygen to hydrogen peroxide (claimed). The composite material is useful in electrochemical catalyst, industrial and domestic applications, sterilizing and eliminating virus and pulp and textile bleaching, waste water treatment, chemical synthesis, semiconductor cleaning and waste gas treatment. ADVANTAGE - The composite material has improved conductivity, electrochemical performance and electro-catalysis performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of titanium dioxide/RGO composite material; catalyst; and cathode material.
