DETAILED DESCRIPTION - Regulating growth of covalent carbon-nitrogen polymerization photocatalyst on two-dimensional honeycomb carbon nanosheet comprises (a) dispersing graphene oxide into water, adding surfactant sodium dodecyl sulfate and reducing agent hydrazine hydrate solution for carrying out reduction reaction for partially reducing graphene oxide to form reduced graphene oxide, then slowly adding 4-cyanodiazobenzene tetrafluoroborate solution, stirring vigorously for 2-3 hours, centrifuging for removing the supernatant, washing the remaining solids with acetone and water for multiple times, and drying to obtain nitrogen-doped two-dimensional honeycomb carbon nanosheets, (b) adding nitrogen-doped two-dimensional honeycomb carbon nanosheets and benzonitrile compounds to the reactor in sequence, then slowly adding trifluoromethanesulfonic acid in a drop wise manner under the protection of inert gas, continuing stirring for 2 hours under ice water bath conditions, where the benzonitrile compounds forms a covalent carbon-nitrogen polymerization photocatalyst under the catalytic action of trifluoromethanesulfonic acid to obtain uniform viscous solution, and (c) placing the homogeneous viscous solution in an oven, maintaining the temperature at 90-110 degrees C for 10-30 minutes, then growing the covalent carbon-nitrogen polymerization photocatalyst generated on the reaction onto the nitrogen-doped two-dimensional honeycomb carbon nanosheet to obtain black colloidal substance, washing the black colloidal substance with water and ethanol for multiple times, and drying.
