Аннотация
Zinc oxide (ZnO) / Tin oxide (SnO2) / Zinc stannate (Zn2SnO4) nanocomposite is prepared via hydrothermal route followed by calcination. The nanocomposite is characterized by X–ray powder diffraction, Fourier Transform Infrared spectroscopy and UV spectroscopy techniques. The nanocomposite’s morphology and the elemental composition is recorded using field emission scanning electron microscopy and energy dispersive X–ray spectroscopy analysis. The nanorods dispersed in the matrix of nanoparticles increases the surface active sites for gas adsorption and this material would be explored as a potential candidate for gas sensing applications at room temperature with quick response and recovery in the near future.
