▎ 摘  要

NOVELTY - A graphitic-tricarbon tetranitride/graphene oxide/nano iron composite visible-light-responsive catalytic membrane comprises graphitic-tricarbon tetranitride/graphene oxide and nano iron in a mass ratio of 100:0.5-1. The mass ratio of graphitic-tricarbon tetranitride and graphene oxide in graphitic-tricarbon tetranitride/graphene oxide is 20-35:100. USE - Graphitic-tricarbon tetranitride/graphene oxide/nano iron composite visible-light-responsive catalytic membrane is used in sewage treatment, wastewater treatment, and water treatment. ADVANTAGE - The graphitic-tricarbon tetranitride/graphene oxide/nano iron composite visible-light-responsive catalytic membrane can be prepared by a simple, economical and feasible method, and has excellent catalytic efficiency in water treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of catalytic membrane, which involves grinding and sintering urea, ultrasonically treating in a water bath, and drying to obtain sheet-shaped graphitic-tricarbon tetranitride (g-C3N4), adding graphene oxide and sheet-shaped g-C3N4 to water, stirring to obtain a suspension, heating the suspension, preparing a composite membrane using the suspension, drying the composite membrane, adding to ferric chloride solution, adding sodium borohydride solution, carrying out liquid-phase reduction, and drying.
