| titleOfInvention | Preparation method for nitrogen and carbon co-doped nanometer titanium dioxide visible-light photocatalyst |
| abstract | The invention relates to a preparation method for nitrogen and carbon co-doped nanometer titanium dioxide visible-light photocatalyst. The preparation method comprises the steps of: taking and adding glacial acetic acid into a container, adding anhydrous ethanol solution of tetrabutyl titanate while agitating to prepare precursor solution, adding the precursor solution into a reaction device, keeping temperature to be 0-20 DEG C, adding ammonium carbonate super-saturated solution while agitating, forming gel after a great amount of white sediment appears, aging and drying to obtain titanium dioxide gel; and heating the titanium dioxide gel at program-controlled temperature in an atmosphere of flowing air, roasting for 1-3h at low temperature and cooling to room temperature to obtain the nitrogen and carbon co-doped nanometer titanium dioxide visible-light photocatalyst. Since conventional equipment and common raw materials are used in the method, the cost is low, the preparation process is simple and the large-scale industrialized production is easy to realize. The prepared photocatalyst particles are even, the grain size is small, the specific surface area is large, the photocatalyst shows high-efficiency photocatalyst degradation activity under the irradiation of visible light, and the degradation rate of rhodamine B within 90min reaches more than 91 percent. |
