The present invention relates to a kind of graphene micro-flowers/nano zinc oxide photocatalysis material and preparation method thereof, include the following steps: first to mix carbon nanotube with graphene oxide solution, ultrasonic disperse, obtains carbon nanotube/graphene oxide suspension；Acetic acid dihydrate zinc solution is added into carbon nanotube/graphene oxide suspension of acquisition again, ultrasonic disperse obtains mixed solution；Spray drying treatment is carried out to the mixed solution of acquisition, obtains powdered product；Powdered product is placed under inert atmosphere, calcine by steps, it is cooling, obtain graphene micro-flowers/nano zinc oxide photocatalysis material.Catalysis material of the invention has the characteristics that absorption, high activity by force under visible light；Meanwhile the problems such as cumbersome technique faced in nanocatalyst, inefficiency are prepared compared to solwution method, spray drying technology prepares catalysis material, simple, efficient, pollution-free. |
