| titleOfInvention | Preparation method and application of high-activity bismuth chromate nano photocatalyst |
| abstract | The invention relates to a preparation method and application of a high-activity bismuth chromate nano photocatalyst, and belongs to the technical field of nano materials. Firstly, dissolving bismuth nitrate pentahydrate and chromium nitrate nonahydrate in a mannitol aqueous solution; dropwise adding a saturated sodium carbonate aqueous solution into the solution, and uniformly stirring to obtain an emulsion; transferring the emulsion to a hydrothermal reaction kettle for hydrothermal reaction, cooling to room temperature, centrifuging, washing and drying to obtain precursor powder, and calcining the precursor powder to obtain the bismuth chromate nano photocatalyst. The bismuth chromate nano photocatalyst prepared by the method has the size ranging from 40 nm to 50nm, the light absorption band edge can be expanded to a red light area, meanwhile, the bismuth chromate nano photocatalyst has high-efficiency photocatalytic pollutant degradation and oxygen generation activity in a visible light area, the oxygen generation quantum efficiency at 600nm reaches 1.52%, and the bismuth chromate nano photocatalyst has very good light stability. The preparation method provided by the method has the advantages of low raw material cost and simple process, is suitable for industrial mass production, and has good application prospect. |
