| titleOfInvention | Preparation method for rare earth element-doped titanium dioxide nano material |
| abstract | The invention relates to a preparation method for a rare earth element-doped titanium dioxide nano material. The method comprises the steps of dissolving urea and rare earth element nitrate in absolute ethyl alcohol; adding liquid titanium source into the above solution to form a homogeneous solution; adding deionized water with stirring to form a transparent gel; performing hydro-thermal treatment on the above gel; washing, filtering and drying to obtain the rare earth element-doped titanium dioxide nano material. An object of doping titanium dioxide by using the rare earth element is realized through automatic regulation and control of pH value of a reaction system by slow decomposition of urea in the hydrothermal process. The preparation method is simple in process and flow, has wide parameter adjustable range, strong repeatability and low cost, and can be used for preparing different rare earth element-doped titanium dioxide nano materials or a plurality of the rare earth elements co-doped titanium dioxide nano material. |
