NOVELTY - A preparation of zinc oxide/graphene/graphene oxide/carbon nanotube aerogel, involves (1) mixing the graphene oxide aqueous solution, the carbon nanotube aqueous solution and the zinc salt solution uniformly, adding the alkaline solution dropwise to the above mixed solution in four times, stirring constantly to make the alkali and the mixed solution fully react to obtain the precursor sol, (2) vacuum filtering the precursor sol obtained in Step (1) to obtain a wet gel, (3) putting the wet gel obtained in step (2) into a freeze dryer for rapid freezing and freeze drying to obtain a zinc hydroxide/graphene oxide/carbon nanotube composite aerogel, (4) putting the zinc hydroxide/graphene oxide/carbon nanotube composite aerogel obtained in step (3) into a thermostat or a tube furnace for heat treatment to decompose the zinc hydroxide into zinc oxide, partially reducing the graphene oxide to graphene. USE - Preparation of zinc oxide/graphene/graphene oxide/carbon nanotube aerogel (claimed) used in photocatalytic material for degrading organic dyes. ADVANTAGE - The aerogel improves the degradation efficiency and degradation rate of the photocatalytic material to degrade organic dyes. DETAILED DESCRIPTION - A preparation of zinc oxide/graphene/graphene oxide/carbon nanotube aerogel, involves (1) mixing the graphene oxide aqueous solution, the carbon nanotube aqueous solution and the zinc salt solution uniformly, adding the alkaline solution dropwise to the above mixed solution in four times, once every 1 minute, 5-10 ml each time, and maintaining the dropping acceleration rate of 5-10 drops per second, stirring constantly to make the alkali and the mixed solution fully react to obtain the precursor sol, (2) vacuum filtering the precursor sol obtained in Step (1) to obtain a wet gel, (3) putting the wet gel obtained in step (2) into a freeze dryer for rapid freezing and freeze drying to obtain a zinc hydroxide/graphene oxide/carbon nanotube composite aerogel, (4) putting the zinc hydroxide/graphene oxide/carbon nanotube composite aerogel obtained in step (3) into a thermostat or a tube furnace for heat treatment for 0.5-4.0 hours to decompose the zinc hydroxide into zinc oxide, partially reducing the graphene oxide to graphene.
