Preparation method of cadmium sulfide/metal oxide composite photocatalyst for efficiently reducing hexavalent chromium |
| abstract |
The invention discloses a preparation method of a cadmium sulfide/metal oxide composite photocatalyst for efficiently reducing hexavalent chromium, and belongs to the field of inorganic nanomaterials. The invention utilizes the atomic-level dispersion property of the metal ions of the layered metal hydroxide laminates, introduces cadmium ions into the layered metal hydroxide laminates and then vulcanizes them to obtain cadmium sulfide, which effectively improves the problem of easy agglomeration of cadmium sulfide nanoparticles. Enhanced photogenerated carrier separation efficiency. The large specific surface area and abundant surface active sites of metal oxides can effectively increase the contact area between catalysts and pollutants, which is beneficial to the improvement of photocatalytic activity. Compared with the single-phase cadmium sulfide photocatalyst, the cadmium sulfide/metal oxide composite photocatalyst prepared by the invention has high catalytic activity, good photochemical stability, simple preparation method, low cost and no secondary pollution, and has high practical application. prospect. |
