| titleOfInvention | A kind of Zinc oxide-base composite photocatalyst nano material and preparation method thereof |
| abstract | Zinc oxide-base composite photocatalyst nano material of the present invention is a kind of material with visible light catalysis activity.This material has the pattern of the solid ball-type of sea urchin shape or hollow ball-type, and preparation method comprises two steps: the alcohol/aqueous solution of (1) zinc salt is placed in autoclave, and 140 – 180 DEG C react 1.5 – 9h; Product ethanol washs, and 60 DEG C of drying 2 – 6h, obtain sea urchin shape ZnO microsphere.(2) utilize dipping-precipitation method, by sea urchin shape ZnO ultrasonic disperse in iron salt solutions, wherein the mass ratio of molysite and ZnO is drip ammoniacal liquor under 0.05 –, 0.2,40 DEG C of stirring conditions to react 1 – 12h; Collect solid and at 350 DEG C roasting 2h obtain α-Fen 2 on 3 nanoparticle modifies ZnO composite photocatalyst system.Material of the present invention has stronger light absorption and photoresponse at visible-range, significantly improves visible light photocatalytic degradation organic dyestuff active, can be used for the photocatalytic degradation process of dying industrial wastewater. |
