Preparation of defective tungsten oxide nanopowder is widely studied as defective tungsten oxide nano powder has wide applications in solar power generation, seawater desalination, and sewage treatment. Defective tungsten oxide nanopowder is a kind of photothermal conversion material, which can convert sunlight into heat energy to heat the base liquid, and realize the photothermal conversion. Specifically, the application of tungsten oxide nanoparticles is to convert water into steam on a large scale under the radiation of the sun or solar…
