Preparation method and application of high-doping-amount metal and sulfur co-doped titanium dioxide photocatalyst |
| abstract |
The preparation method of the titanium dioxide photocatalyst co-doped with metal and sulfur with high doping amount comprises the steps of adopting organic titanium alkoxide as a titanium source, adopting nano metal powder as a metal source, adopting DMSO as a reaction solvent, and introducing H 2 S is used as an auxiliary agent, and primary forming of the titanium dioxide photocatalyst is completed through stirring reaction, wherein the titanium dioxide photocatalyst contains 2-3 v% of H 2 Quenching in argon of S for more than 3 times to prepare the high-doping-amount metal and sulfur co-doped titanium dioxide photocatalyst, wherein the doping amount of the metal and the nonmetal is obviously improved compared with the known titanium dioxide photocatalyst with the best photocatalytic effect; compared with the known titanium dioxide photocatalyst with the best photocatalytic effect and the highest metal doping amount, the metal doping amount is obviously improved; compared with the known titanium dioxide photocatalyst with the best photocatalytic effect and the highest non-metal doping amount, the titanium dioxide photocatalyst has the advantages that the non-metal doping amount is obviously improved, the visible light activated catalytic capability and the virus killing and inactivating effects are better, and the titanium dioxide photocatalyst can be applied to killing germs, inactivating viruses and degrading organic pollutants. |
