| titleOfInvention | Bismuth/rhodium co-doped titanium dioxide composite material, preparation method and photocatalytic application thereof |
| abstract | The invention discloses a bismuth/rhodium co-doped titanium dioxide composite material, a preparation method and a photocatalysis application thereof. In the invention, Rh (IV) solution is prepared by oxidizing Rh (III) with sodium bismuthate under acidic condition, Rh (IV) is doped into TiO by in-situ replacement by using hydrothermal synthesis method as precursor 2 Preparing bismuth and rhodium co-doped TiO in the material 2 A composite material. The color of the composite material is related to the doping ratio of Rh (IV), and as the doping ratio of Rh (IV) is increased, Bi, Rh-TiO 2 Also gradually changes from white to yellow, yellow-green, gray to black. Bi, Rh (IV) -TiO 2 The optical forbidden band width of the material is about 2.76-2.90 eV, and the material shows good visible light catalytic performance. Bi, Rh (IV) -TiO 2 The material is obviously better than undoped TiO in the decomposition of acetic acid under the excitation of visible light with the wavelength of more than 400nm 2 And when rh (iv)/Ti =0.22 mol%. Bi, Rh (IV) -TiO excited by visible light with wavelength more than 450nm 2 The material has obviously better decomposition to isopropanol than undoped TiO 2 And commercial FP6 and P25. |
