Novel Hydrothermal synthesis and characteristics of thin films V2O5@TeO2 with CTAB for detection of NO2 gas
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2019, Vol 3, Issue 5
Abstract
Novel thin films V2O5 @TeO2 prepared with hexadecyl trimethyl ammonium bromide (CTAB) by hydrothermal method at (160oC) were fabricated successfully on glass substrates. Also, used as the parameters to control morphology by hydrothermal technique. At room temperature and annealing by tubular quartz furnace at temperature (473,673) K for 8 hours with air. Their NO2 gas sensing properties were examined at a different annealing temperature and showed promising sensitivity and response towards tested gas. The polycrystalline nature of the obtained films was confirmed by XRD diffraction. Surface morphology was studied using field emission scanning electron microscopy FESEM, Energy‐dispersive X‐ray spectroscopy, and atomic force microscopy AFM. After annealing, the roughness of the surface and the mean grain size were increased annealing temperature
