| titleOfInvention | Nano tungsten oxide and preparation method and application thereof |
| abstract | The invention provides a nano tungsten oxide and a preparation method and application thereof. The preparation method of the nano tungsten oxide comprises the following steps: 1) dispersing tungsten hexachloride in an organic alkane solvent to obtain a dispersion liquid; 2) stirring the dispersion liquid in air or oxygen atmosphere to obtain an oxygen-containing precursor, sealing, reacting at 160-280 ℃ for 6-24 h, and obtaining a precipitate which is the nano tungsten oxide; the stirring speed is 200-500 r/min, and the stirring time is 3-6 h. The preparation method provided by the invention is simple, convenient and feasible, green and environment-friendly, the raw materials are easy to obtain, the controllability is high, and the obtained nano tungsten oxide has uniform size, no agglomeration and good photocatalytic performance, so that the method can be widely applied to the fields of photocatalytic degradation of dyes and other semiconductor photocatalysis. |
