WO 3 is a traditional type of NO 2 -sensing material. There are still some problems in relevant studies, such as high detection limit, high working temperature, and complex process. In this paper, simple hydrothermal method was used to prepare monoclinic WO 3 (M-WO 3 ), triclinic WO 3 (T-WO 3 ), and...
