| titleOfInvention | Preparation method of tungsten trioxide for catalyzing photodegradation of organic matters |
| abstract | The invention discloses a preparation method of tungsten trioxide for catalyzing photodegradation of organic matters, and relates to the technical field of chemical catalysis. The method comprises the following steps: generating a precursor by using a wet chemical precipitation method of a tungsten solution and an acid solution, and calcining the precursor to obtain powdery nano tungsten trioxide particles; and (3) carrying out surface disordering treatment on the nano tungsten trioxide particles in an alkali metal solution to obtain the tungsten trioxide nano crystal for catalyzing the photodegradation of the organic matters. The preparation method of the invention enables the tungsten trioxide nano-particles which do not respond to visible light wave bands originally to have the photocatalytic activity of the visible light wave bands. The technical scheme of the invention is efficient and feasible, has low cost, and can effectively solve the problem of the catalyst in the visible light-near infrared band. |
