Abstract

A preparation method of carbon nitride modified with perylenetetracarboxylic dianhydride/graphene oxide aerogel composite material includes: (1) preparing carbon nitride nanosheets by calcination using dicyandiamide as raw material; (2) reacting perylenetetracarboxylic dianhydride and carbon nitride nanosheets in imidazole to prepare carbon nitride modified with perylenetetracarboxylic dianhydride; (3) dispersing said carbon nitride modified with perylenetetracarboxylic dianhydride and graphene oxide into deionized water, freeze-drying after the reaction to obtain carbon nitride modified with perylenetetracarboxylic dianhydride/graphene oxide aerogel composite material.
