A kind of preparation method of black titanium dioxide material with photothermal enhanced photocatalysis |
| abstract |
The invention provides a preparation method of a photothermally enhanced photocatalytic black titanium dioxide material, which relates to the modification of TiO2 and the technical field of photocatalytic application thereof. The titanium hydride raw material powder is prepared into a TiH 2 suspension and oxidatively dried to obtain a TiOOH precursor powder, which is then calcined at high temperature to obtain a black TiO 2 powder. The black TiO 2 prepared by the invention has a broad-spectrum light absorption ability, and has a strong light absorption ability in the wavelength range of 250-2000 nm, so that it has a certain photothermal effect; the photocatalytic performance of the black TiO 2 prepared by the invention has been compared big boost. In the present invention, by comparing different calcination temperatures, the calcination temperature and calcination time with the best photothermal enhancement photocatalytic performance are obtained. Compared with the existing reduction preparation method, the present invention has the advantages of simple preparation process, safety and low cost. |
