The need to detect CO2 gas is increasing with increasing the environmental concerns. To date, IR absorption detectors and MS are mainly used for sensing carbon dioxide gas, however these are required a high maintenance costs. In contrast, electrochemical sensors can be produced at low cost however their preparations are complicated and vulnerable to humidity interference. The present study was attempted to overcome these weaknesses by preparing BaSnO3 nanowire (BSO NW) with outstanding gas sensing properties. The perovskite crystal structure of the BSO facilitates this materials to exhibit high CO2 gas sensing performance. Indeed, the high specific surface area and improved porous structure of BSO NW sensor increased its sensitivity toward CO2 sensing. The properties of the gas sensor was examined by scanning electron microscopy (SEM), X-Ray diffraction (XRD), thermal gravimetric analysis (TGA) and resistance test device. |
