摘要：
The gas sensors of semiconducting metal oxide are commonly deemed to be a promising sensor type. This work introduces a synthesizing method for SnWO4 sensor with coral-like by simple hydrothermal strategy. The acquired SnWO4 products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). Tests revealed scheelite SnWO4 sample was successfully prepared and the vacancy oxygen and lattice oxygen respectively accounted for 74.35% and 25.65% in the oxygen element distribution. The gas sensing performances of SnWO4 coral-like were investigated via static gas sensor testing system. What's more, the response of SnWO4 sensor to 200 ppm triethylamine (TEA) is 17.58 at the optimum operating temperature (240 degrees C). And it expresses unique selectivity and long-term stability to triethylamine (TEA). This paper proves for the first time that SnWO4 nanomaterial can be used as a noval material in gas sensor field.
