Optimum Working

Nano-SnO2powder was prepared by the hydrothermal method in this paper. X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the composition of the crystalline phase and the morphology of the prepared gas-sensitive materials, respectively. In particular, the study focused on the sensing behaviors of nano-SnO2-based sensor towards power transformer fault gases such as hydrogen and carbon monoxide. The optimum working temperature for hydrogen and carbon monoxide is about 400∘C and 360∘C, separately. Further investigations into the adsorption process of gas molecule on SnO2(110) surface based on the first principles were conducted. The calculations indicated that 1σorbits of H2split into several new electronic peaks and 5σorbits of CO almost degenerated completely in the adsorption process, which promoted charge transfer between gas molecule and SnO2(110) surface. It provides a qualitative explanation for the prepared nano-SnO2-based sensor exhibiting different gas sensing properties towards H2and CO.
