| titleOfInvention | Double-sensitized titanium dioxide photocatalyst and preparation method thereof |
| abstract | The invention discloses a double-sensitized titanium dioxide photocatalyst and a preparation method thereof, wherein the photocatalyst is Pt-WO 3 ‑TiO 2 the-CdS mesoporous hollow sphere has a spherical shell of Pt-WO in sequence from inside to outside 3 Layer, TiO 2 A layer, a CdS layer; the catalyst is prepared by a layer-by-layer coating method. The mesoporous hollow sphere of the invention utilizes CdS to sensitize TiO 2 Using the conduction band of WO 3 Sensitized TiO 2 Valence band of (3), promotion of WO by Pt 3 Separation of the photogenerated electrons and the holes, and finally respectively exciting WO by utilizing two photons of visible light 3 And CdS, the photocatalytic reaction still being in TiO by separation of photo-generated electrons from holes 2 Surface generation, equivalent to exciting TiO with one ultraviolet photon 2 The effect of photo-generated electron/hole pairs is obtained. The mesoporous hollow sphere structure has the characteristic of visible light response, and is expected to be applied to numerous fields such as photocatalytic degradation of organic pollutants under visible light, hydrogen production by water photolysis, solar cells and the like. |
