▎ 摘　　要

NOVELTY - A two-dimensional porous graphene/cuprous oxide composite material is prepared by adding copper chloride dihydrate into graphene oxide aqueous dispersion, ultrasonicating for 5-30 minutes, filtering, drying at 40-60 degrees C, performing ignition combustion to obtain porous graphene covered with brick red cuprous oxide, or calcining to obtain crude product, washing, and drying. USE - Method for preparing two-dimensional porous graphene/cuprous oxide composite material used as catalyst for catalytic oxidation of luminol with hydrogen peroxide to produce chemiluminescence reactions (claimed). ADVANTAGE - The product has good linear relationship between the logarithmic values of the chemiluminescence intensity at 425 nm in the catalytic oxidation of luminol by hydrogen peroxide with linear range of 1.0x 10 8 to 8.0x 10 4 M, and has broad application prospect in the fields of catalysis, biochemical analysis and detection.
