Cerium-based solid solution and its preparation method and use |
| abstract |
The invention provides a cerium-based solid solution, a preparation method and application thereof. The preparation method of the cerium-based solid solution comprises the following steps: (1) forming a mixed solution of a soluble cerium salt and a soluble metal M salt, and reacting the mixed solution with an alkaline precipitant to obtain a precursor of the cerium-based solid solution; (2) mixing the cerium The precursor of the cerium-based solid solution is calcined at 150-370° C. to obtain the cerium-based solid solution. The preparation method of the invention has a low calcining temperature, and the obtained cerium-based solid solution has a good degradation effect on organic dyes. |
