▎ 摘 要
NOVELTY - Ultrasonic preparation of cuprous oxide at carbon/graphene hybrid material is carried out by reacting reduced graphene oxide, pyrene derivative and cupric salt in organic solvent under ultrasonic water bath condition, and filtering reaction liquid in vacuum to obtain the product. USE - Method for ultrasonic preparation of cuprous oxide at carbon /graphene hybrid material (claimed). ADVANTAGE - The method has simple and easy operation and low cost. The obtained hybrid material has high quality, excellent performance, high uniformity, and low impurity content.
