| titleOfInvention | Silicon-doped zinc tungstate/zinc oxide composite material, preparation method and application thereof |
| abstract | The composite material is prepared by mixing phosphotungstic acid and silicotungstic acid in a mass ratio of 1: 1-6, and zinc nitrate and phosphotungstic acid in a molar ratio of 200-300: 1; the doping amount of the silicon is 0.2-0.8%. The preparation method comprises the following steps: (1) dissolving phosphotungstic acid and silicotungstic acid in a methanol solution of 2-methylimidazole, and mixing and stirring; (2) adding zinc nitrate methanol solution, mixing uniformly, standing, centrifuging, washing and drying; (3) and calcining in an oxidizing atmosphere to obtain the catalyst. The invention also discloses an application of the composite material. The composite material is bowl-shaped particles, the average particle size of the particles is 120-160 nm, the thickness of the bowl wall is 10-20 nm, the catalytic degradation effect in 90min under visible light is up to 92%, and the catalytic degradation effect is still up to 86% after the composite material is repeatedly used for 4 times; the method is simple, low in cost and suitable for industrial production. |
