Abstract:High quality 3%Cu-SnO2 nanoparticles have been prepared onto the glass substrate by using novel and economical ultrasonic spray pyrolysis technique. The X-ray diffraction patterns showed that 3% Cu-SnO2 nanoparticles formed in tetragonal rutile structure. The intensities of peaks shown by X-ray pattern were indexed as (110), (101), (200) and (211). The microstructure, surface morphology, particle size and elemental properties of 3%Cu-SnO2 nanoparticles were characterized using, scanning electron microscope (SEM), and Transmission electron microscopy (TEM). These nanoparticles were tested for H2S sensors applications. It was observed that 3% Cu-SnO2 nanoparticles exhibited remarkable sensitivity to H2S (200 ppm) gas at 150ºC, more precisely showing good response and recovery.
