Abstract Herein, we report the synthesis of BaSnO3 (BSO) from molten salts (BSO1) and test its efficacy as an ethanol sensor, for the first time. BSO was also synthesized using a more well-established coprecipitation method (BSO2), and the influence of the synthesis method on morphology, microstructure and surface chemical composition of BSO was compared using electron microscopy, x-ray diffraction and photoelectron spectroscopy. Both BSO1 and BSO2 exhibited their best responses to 100 ppm of ethanol at 260 °C, but BSO1 showed higher response (12.5) and lower detection limit (0.5 ppm) compared to those of BSO2 (8.2 and 1 ppm) suggesting its superior ethanol sensing properties. The improved sensing of BSO1 was correlated with the corresponding surface morphology and chemical composition.

合成方法对锡酸钡微观结构和乙醇传感性能的影响

摘要 在此，我们首次报道了从熔盐 (BSO1) 合成 BaSnO3 (BSO) 并测试其作为乙醇传感器的功效。还使用更成熟的共沉淀法 (BSO2) 合成 BSO，并使用电子显微镜、X 射线衍射和光电子能谱比较了合成方法对 BSO 的形态、微观结构和表面化学成分的影响。BSO1 和 BSO2 在 260 °C 下对 100 ppm 乙醇表现出最佳响应，但与 BSO2（8.2 和 1 ppm）相比，BSO1 显示出更高的响应（12.5）和更低的检测限（0.5 ppm），表明其具有卓越的乙醇传感特性。BSO1 的改进传感与相应的表面形态和化学成分相关。
