摘要: Barium stannate, BaSnO3, an n-type semiconducting oxide with cubic perovskite structure, has been prepared by the thermal decomposition of barium carbonate (BaCO3) and tin tetrahydroxide (Sn(OH)4). The material was characterized various physical techniques such as differential analysis (DTA/TG), X-ray diffraction (XRD), BET surface area, Fourier transform infra-red (FT-IR) spectroscopy scanning electron microscopy (SEM). Of its several applications, this proven to be one successful candidates for detection liquefied petroleum gas (LPG). sensor a very good selectivity detect LPG in comparison other reducing gases, like carbon monoxide methane.
