▎ 摘　　要

NOVELTY - Preparing cuprous oxide/titanium dioxide/graphene oxide ternary nanocomposite comprises (1) dissolving copper sulfate, titanium sulfate and sodium acetate in distilled water in the mass ratio of 1:0.5:10, in order to obtain mixed solution A, (2) adding graphene oxide into mixed solution A, and controlling the mass ratio of graphene oxide to copper sulfate to be 5:1, stirring evenly to obtain suspension B, and (3) transferring the suspension B to a hydrothermal reaction kettle, seal it, and performing a forced hydrolysis reaction and a hydrothermal redox reaction at 160-200°C, after reacting for 3-20 hours, natural cooling, centrifugal separation, washing, and vacuum drying to obtain the cuprous oxide/titanium dioxide/graphene oxide ternary nanocomposite. USE - The method is useful for preparing cuprous oxide/titanium dioxide/graphene oxide ternary nanocomposite. ADVANTAGE - The method: has simple preparation technique, good operability, no pollution, no side reaction, high product purity, and easily available raw materials. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a preparing cuprous oxide/titanium dioxide/graphene oxide ternary nano-composite (Drawing includes non-English language text).
