In-situ non-metallic element and rare earth element co-doped strontium titanate catalyst and preparation method and application thereof |
| abstract |
The present application provides an in-situ non-metallic element and rare earth element co-doped strontium titanate catalyst and a preparation method and application thereof. The in-situ non-metallic element and rare earth element co-doped strontium titanate catalyst has the general formula: Sr 1‑y RE y TiO 3‑i X i . The preparation method comprises the following steps: performing a first reaction on a titanium-containing compound containing element X and an oxidant to obtain a first reaction precursor; performing a second reaction on a strontium-containing material and the first reaction precursor to obtain a second reaction precursor; The reaction precursor and the element-containing RE material are subjected to a third reaction, and then the pH of the system is adjusted to alkaline to obtain a third reaction precursor; the third reaction precursor is subjected to a solvothermal reaction, and post-processing is performed to obtain in-situ non-metallic elements and rare earth elements Co-doped strontium titanate catalyst. The in-situ non-metallic element and rare earth element co-doped strontium titanate catalyst provided by the present application has a strong visible-near-infrared light absorption rate and a good UV-visible light excitation catalytic effect. |
