| titleOfInvention | Defect-state tungsten oxide nanoparticle photothermal conversion material and preparation method and application thereof |
| abstract | The invention relates to a defect-state tungsten oxide nanoparticle photothermal conversion material and a preparation method and application thereof. The preparation method comprises the following steps: (1) adding a tungsten source, citric acid and glucose into deionized water according to a certain proportion, fully stirring to obtain a mixed solution, dropwise adding hydrochloric acid into the mixed solution to adjust the pH value of the mixed solution to 0-1, heating the mixed solution to react for 12-48h, and washing and drying after the reaction is finished to obtain a hydrated oxide precursor with oxygen defects; (2) and calcining the hydrated oxide precursor, and cooling to room temperature after the calcination is finished to obtain the hydrated oxide. The application is to convert water into steam in large scale under the radiation of the sun or a solar simulator so as to realize solar power generation, seawater desalination or sewage treatment. The invention has the advantages that the provided photothermal conversion material can convert sunlight into heat energy to heat the base liquid, thereby realizing photothermal conversion; the invention uses the tungsten oxide nanoparticles in the defect state for the conversion of solar energy into heat energy for the first time and finds that the tungsten oxide nanoparticles have the potential for large-scale application. |
