Synthesis and gas sensing performance of NiO decorated SnO2 vertical-standing nanotubes composite thin films

In this work, a new type NiO decorated SnO2 vertical-standing nanotubes composite thin film was synthesized successfully via a facile hydrothermal method. The microstructure, physico-chemical surface state and morphology of the composite thin film were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM), respectively. The results showed that the NiO decorated SnO2...
