NOVELTY - Use of graphene/azepine graphene-cobalt ferrite intelligent photocatalyst in selective adsorption and catalytic denitrification, is claimed. USE - The photocatalyst is useful in selective adsorption and catalytic denitrification (claimed). ADVANTAGE - The photocatalyst has simple preparation method, is easy to control, and greatly improves production efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene/azepine graphene-cobalt ferrite intelligent photocatalyst comprising dissolving soluble cobalt salts, soluble iron salts and graphene or azatriene graphene in solvent, then uniformly mixing, adjusting the mixed solution pH to basic, then reacting the mixed solution at 150-200 degrees C for 6-10 hours to obtain final product.
