| titleOfInvention | Preparation method of tungsten oxide bismuth nano photocatalyst |
| abstract | The invention belongs to the field of photocatalysts, and particularly relates to a preparation method of a tungsten oxide bismuth nano photocatalyst. The method comprises the following steps: preparing a PTA solution A with the concentration of 0.05-0.2 mol/L and a bismuth nitrate solution B with the concentration of 0.1-0.2 mol/L; dropwise adding the solution B into the solution A according to the molar ratio of the solution A to the solution B of 1: 1-1: 1.5 to obtain a solution C; adjusting the pH value of the solution C to 1.8-2.2 to obtain a solution D; adding the solution D into a hydrothermal reaction kettle, wherein the filling degree is 60-75%, the temperature is 140-180 ℃, the time is 8-12 h, and cooling to room temperature; and opening the reaction kettle, cleaning the product for 3-5 times by using deionized water and absolute ethyl alcohol, and drying at 80-100 ℃ until the weight is not reduced any more, thus obtaining the product. The method has the advantages of simple process, easily controlled preparation conditions, low cost, high product purity, good crystallinity and high photocatalytic activity. |
