▎ 摘　　要

NOVELTY - Molybdenum dioxide/nitrogen-doped reduced graphene full spectrum response photo-catalyst is claimed. The photo-catalyst is nitrogen-doped reduced graphene oxide-supported molybdenum dioxide composite and the mass ratio of the supported molybdenum dioxide is 90-99.9%. USE - The full-spectrum response photo-catalyst is useful for photo-catalytic degradation and removal of organic dyes under ultraviolet, visible and near-infrared light irradiation (claimed); and in the treatment of organic dye water pollution. ADVANTAGE - The full-spectrum response photo-catalyst enhances photocatalytic adsorption, and improves photocatalytic efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing photo-catalyst, comprising (i) preparing graphene oxide hydrosol, (ii) mixing graphene oxide hydrosol with molybdate, organic fuel and combustion promoter for combustion to obtain precursor, and (iii) performing heat treatment of the precursor under reducing atmosphere.
