A kind of preparation method of WO3/BiOBr photocatalytic nanometer material |
| abstract |
The invention discloses a preparation method of WO 3 /BiOBr photocatalytic nanometer material. The present invention adopts hydrophilic polymer sodium polyacrylate and cationic polyacrylamide to cross-link in aqueous solution to form a gel, which limits the growth of WO 3 /BiOBr material, and can obtain WO 3 with a size of 12-18nm and good dispersibility. /BiOBr nanomaterials, and has excellent catalytic degradation performance of rhodamine B. |
