▎ 摘　　要

NOVELTY - A copper oxide reducing method involves drying the graphene and copper oxide in an oven, drying at certain temperature, cooling to room temperature, weighing a certain proportion of graphene copper oxide, grinding evenly, evenly loading into the test tube, connecting the reaction device and heating, observing the experimental phenomenon, and recording the experimental results, drying at 60-200 degrees C for 30-100 minutes, where the graphene to the copper oxide reactant at a ratio of 1:5-1:15. USE - Method for reducing copper oxide. ADVANTAGE - The method enables reducing copper oxide with improved characteristic phenomenon of the charcoal reduction copper oxide experiment, and improves the success rate and the student creative thinking of culture.
