NOVELTY - Preparation of cuprous oxide/oxidized graphene nano-composite involves (s1) dissolving divalent copper salt and sodium acetate in distilled water sequentially in a molar ratio of 1:6 to obtain mixed solution (A), (s2) adding oxidized graphene into obtained solution, controlling the mass ratio of the oxidized graphene and divalent copper salt to 5:1, and stirring uniformly to obtain suspension (B), and (s3) transferring the suspension (B) to hydrothermal reactor, sealing, performing hydrothermal redox reaction at 140-200℃ for 2-10 hours, naturally cooling, centrifugally separating, washing, and vacuum-drying. USE - Preparation of cuprous oxide/oxidized graphene nano-composite. ADVANTAGE - The method has simple preparation process, excellent operability, pollution-free, no side reaction, high product purity, and easily obtainable raw material.
