Trirutile zinc antimonate (ZnSbO) nano-cubes/cuboids have been fabricated by a sol-gel spin-coating method using polyethylene glycol (PEG) as the structure-directing agent. The fabricated films were characterized for surface morphology, along with structural, FT-IR and thermal analysis. The crystallite size of ZnSbO is found to be 35 nm. The fabricated films have been tested for the detection of liquefied petroleum gas (LPG) and carbon dioxide (CO) gas leakage at room temperature (27 °C). They exhibit fairly high sensitivity (1.73), low response and recovery times (∼41 and 95 s, respectively), and good reproducibility and stability (99.2%) at room temperature for the detection of LPG leakage. Based on these observations, the fabricated film has the potential to be used as a LPG sensor at room temperature.
采用溶胶-凝胶旋涂法，以聚乙二醇（PEG）作为结构导向剂，制备了三方锑酸锌（ZnSbO）纳米立方体/长方体。对制备的薄膜进行了表面形貌表征，以及结构、傅里叶变换红外光谱（FT-IR）和热分析。发现ZnSbO的微晶尺寸为35nm。对制备的薄膜进行了测试，以检测室温（27°C）下液化石油气（LPG）和二氧化碳（CO）气体的泄漏情况。它们在室温下对LPG泄漏检测表现出相当高的灵敏度（1.73）、较低的响应和恢复时间（分别约为41秒和95秒），以及良好的重现性和稳定性（99.2%）。基于这些观察结果，制备的薄膜有潜力在室温下用作LPG传感器。
