摘要：
WO3-based semiconductor gas sensor attracts much attention nowadays. It is widely used for detection of NO2, O3, H2S, NH3, etc. WO3-based semiconductor gas sensors are categorized into four types: pure WO3, composite oxide, noble metal activated metal oxides and polymer-metal oxides. This review presents new advancements in sensing properties of these WO3-based gas sensors. Based on the published results, it is suggested that the development of new nanostructured materials, reduction in working temperature and improvement in selectivity should be emphasized for the future work on WO3-based gas sensors. © 2016, Materials Review Magazine.
