NOVELTY - A cuprous oxide-lead oxide/graphene oxide composite powder comprises 10-30 wt.% cuprous oxide and 30-60 wt.% lead oxide, loaded on the surface of 20-40 wt.% graphene oxide. USE - Cuprous oxide-lead oxide/graphene oxide composite powder is useful as combustion catalyst (claimed). ADVANTAGE - The cuprous oxide-lead oxide/graphene oxide composite powder has excellent catalytic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of cuprous oxide-lead oxide/graphene oxide composite powder, which involves preparing 0.5-2 mol/L dilute nitric acid solution of soluble lead salt and soluble copper salt, adding graphene oxide to water, adding polyethylene glycol 400, ultrasonically dispersing, adding the salt solution, stirring, adjusting pH to 9.5-10.5 by addition of alkali solution, fully stirring, filtering, washing, drying at 250-350 degrees C under inert-gas protection, and calcining.
