Abstract
The NiO doped SnO2 composite nano-particle powder was prepared by chemical co-precipitation method.The composition
particle size and morphology of the sample were characterized by X-ray diffraction (XRD)
transmission electron microscope(TEM)and scanning electron microscope(SEM).Gas sensing properties of the sample was tested.The results indicated that the composite nano-particle powder had high sensitivity to formaldehyde and excellent selectivity to ethanol at the working temperature of 95℃.
