Abstract

The NiO nanosheets assembled hollow spheres have been synthesized by a facile precipitation method using SiO2 spheres as hard template, and the Fe was doped into NiO to improve the sensing properties of triethylamine (TEA). The structure, morphology and gas sensing properties of undoped and doped NiO were characterized by various analysis methods. The results show that the NiO microspheres have large specific surface, and excellent sensing response to 10 ppm triethylamine, so, it is a promising sensing material for detection of TEA.
