▎ 摘  要

NOVELTY - Graphene/graphitic carbon nitride three-dimensional network composite film comprises graphene as a carrier and nano-sheet graphitic carbon nitride, where nano-sheet graphitic carbon nitride is distributed on the surface of the graphene. USE - The composite film is useful in photocatalytic degradation of pollutants (claimed). ADVANTAGE - The method: is simple, the composite film has high adsorption characteristics of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite film comprising (i) adding graphene oxide and nano-sheet graphitic carbon nitride into de-ionized water and subjecting to ultrasonic dispersion to obtain graphene oxide/ graphitic carbon nitride mixed dispersion, (ii) filtering graphene oxide/graphitic carbon nitride mixed dispersion film through film to obtain composite film, reducing, washing, then drying to obtain dry film, and (iii) applying voltage to dried film to obtain final product.
