- Abstract
CNT-ZnO nanocomposite powders were synthesized by addition of carbon nanotubes (CNT) during the growth of ZnO nanoparticles using a wet-chemical method. These CNT-ZnO nanocomposites powder were then spin coated on corning glass substrates to obtain thin films which were characterized using X-ray diffraction, scanning electron microscopy and current voltage characteristics. Hydrogen sensing (50- 1000 ppm) carried out on pure and CNT-ZnO nanocomposites at operating temperature of 250 and 300°C in atmosphere (0.4±0.03 mbar) revealed higher sensitivity in 2 wt.% CNT-ZnO nanocomposite thin film compared to the pure ZnO thin film.
