A review on WO3 based gas sensors: Morphology control and enhanced sensing properties
Abstract
Abstract Tungsten oxide (WO3), a typical n-type gas-sensing material, has attracted considerable attention to detect various hazardous gases. Previous studies indicated that unique nanostructures are highly related to the sensing performances. So far, great advances have been achieved to design and fabricate diverse WO3 in different dimensional. However, it is still challenging to achieve high performances. To significantly enhance the gas-sensing properties, many strategies have been explored. In this review, the general approaches to tune the morphologies of WO3 are analyzed. Then, much more attention is particularly paid to improve the sensing-properties of WO3 based gas sensors. Firstly, the fundamental of WO3 based gas sensors is described. Secondly, various progresses to control the morphologies in 0-dimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) WO3 will be reviewed. Thirdly, the efficient strategies for the enhancement of gas-sensing properties based on WO3 will be discussed. Meanwhile, the enhancement mechanisms are taken into account as well. Finally, a perspective on the further development for WO3 synthesis and applications in gas sensors is proposed as well.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
