| titleOfInvention | SiO2 supported s-doped TiO2 visible light catalyst and preparation method thereof |
| abstract | The invention relates to an SiO2 supported s-doped TiO2 visible light catalyst and a preparation method thereof. Through organic combination of nonmetallic ion doping and porous carrier suppoting, the preparation method employs a liquid phase hydrolysis method to coat SiO2 microballoons with a titanium predecessor, and then conducts modification by nonmetallic S doping, so that an S-doped TiSxOy/SiO2 visible light catalyst with good dispersity and a crystal grain size of 8-30nm can be obtained By doping S on the surface of TiO2 to form a new energy level structure, the catalyst absorption bathochromic-shift is changed to 450-550nm. A proper amount of S doping not only can realize the visible light catalytic activity of TiO2/SiO2, but also improves the ultraviolet light catalytic activity substantially. Besides, SiO2 supporting can improve TiO2 particle conglomeration and the separating property of the TiO2 catalyst, thus being convenient for the post processing of the catalyst. |
