▎ 摘　　要

NOVELTY - Preparation of graphene oxide/copper oxide-copper quantum dot absorbing material involves mixing 0.2-2 mg/ml graphene oxide solution and solution of copper chloride dihydrate in mass ratio of 1:0.8-8, stirring for 30 minutes, ultrasonically dispersing for 30 minutes, adding sodium borohydride dissolved in 50-200 ml water, such that the mass ratio of graphene oxide solution and sodium borohydride is 1:5-15, reacting at room temperature for 3-4 hours, centrifuging and forming black precipitate, washing using deionized water for 2-3 times, and drying at 40-80 degrees C. USE - Preparation of graphene oxide/copper oxide-copper quantum dot absorbing material (claimed). ADVANTAGE - The method efficiently and economically provides graphene oxide/copper oxide-copper quantum dot absorbing material has high adsorption effect with different wavelengths.
