| Abstract: | WO3 film is a kind of smart material, which has been widely applied in electrochromism as well as electrcatalysis and gas sensing materials. In the paper, the preparation method of nano-WO3 film and its advantages and disadvantages are reviewed. The application of WO3 sensing-film and gas sensing mechanism are reviewed. Different dopings have different effects on gas sensitivity. Some opinions about the future research trend of WO3 are proposed. |
