▎ 摘 要
NOVELTY - Graphene-porous nickel oxide composite catalyst comprises graphene support and porous nickel oxide supported on the graphene support, where the mass ratio of the graphene support to the porous nickel oxide is 19:1-1:19, preferably 10:1-1:10. USE - Graphene-porous nickel oxide composite catalyst used for treating wastewater, deep treatment of industrial waste water by sodium hypochlorite oxidation or ozone oxidation (all claimed). ADVANTAGE - The graphene-porous nickel oxide composite catalyst enables organic pollutant degradation.
