摘要：

Ammonia gas sensors that work at room temperature are of immediate requirement to monitor the environmental safety of human beings and other living organisms. In the present study, we report the room temperature ammonia-sensing performances of Co3O4 and NiCo2O4 nanoparticles. The hydrothermally prepared samples were characterized using various sophisticated techniques in order to investigate the crystal structure, phase purity, morphology, elemental and chemical composition. The as prepared samples displayed selectivity against the ammonia gas and the NiCo2O4 nanorod-like sample exhibited superior sensing performances at room temperature.
