A preparation method of flower spherical ErBO3 photocatalyst composed of multi-layered petals |
| abstract |
The invention discloses a method for preparing flower-shaped ErBO 3 photocatalyst composed of multi-layered petals. The ErBO 3 powder is synthesized by a hydrothermal method, which includes the following steps: S1: Slowly add HNO₃ solution into erbium oxide, and simultaneously carry out Heat up and stir until the erbium oxide is completely dissolved to obtain solution A; S2: Mix and heat boric acid and water to obtain solution B; S3: Mix and heat solution A and solution B to obtain solution C, and slowly add alkali to the cooled solution C neutral solution until the solution C is weakly alkaline; S4: After the weakly alkaline solution C is heated and reacted, the precipitate in solution C is separated from the clear liquid and dried to obtain a flower-shaped ErBO composed of multi-layered petals. 3 photocatalyst. |
