Preparation of Defective Tungsten Oxide Nanopowder

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 simulator to achieve solar power generation, seawater desalination, or sewage treatment. Well, do you know how to prepare defective tungsten oxide nanoparticles?

Preparation of Defective Tungsten Oxide Nanopowder

Add tungsten source, citric acid and glucose to deionized water according to a certain ratio and fully stir to obtain a mixed solution, add hydrochloric acid dropwise to the mixed solution to adjust its pH value to 0-1, and then raise the temperature of the mixed solution to react 12-48 h, after the reaction is completed, washing and drying to obtain an oxygen-deficient hydrated oxide precursor; calcining the hydrated oxide precursor, and cooling to room temperature to obtain defective tungsten oxide nanoparticles.
