| titleOfInvention | Preparation method of copper-doped tungsten trioxide composite nanofiber material |
| abstract | The invention discloses a preparation method of a copper-doped tungsten trioxide composite nanofiber material, which comprises the following steps: s1, dissolving ammonium metatungstate in water, adding polyvinylpyrrolidone, and stirring to obtain a precursor solution; s2, performing electrostatic spinning on the precursor solution in the S1 to obtain a primary spun fiber; s3, calcining the spun fiber prepared in the S2, and cooling to obtain tungsten trioxide nano fiber; s4, soaking the tungsten trioxide nano-fibers in the S3 in a copper salt solution, and calcining to obtain the fiber material. The method provided by the invention is simple and easy to implement, the parameters can be accurately controlled, the cost is low, and the method is green and environment-friendly; the prepared copper-doped tungsten trioxide composite nanofiber has the advantages of uniform diameter distribution, large length-diameter ratio and stable appearance, and meanwhile, the copper doping greatly improves the photocatalytic degradation performance of tungsten trioxide, has excellent aniline degradation performance, and has great application prospect in the field of water pollution. |
