MoO3, WO3 Single and Binary Oxide Prepared by Sol-Gel Method for Gas Sensing Applications
Source abstract
Abstract
MoO3, WO3 single and Mo/W binary compounds at different Mo/W atomic percentages were deposited by sol-gel spin coating technique on Si/Si3N4 substrates provided with Pt interdigital electrodes and annealed at 450°C for 1 h. Films were characterized by SEM, grazing incidence XRD and XPS techniques. Electrical responses to different gases were obtained by exposing the films to 30 ppm CO and 1 ppm NO2. Increasing the Mo/W content the selectivity to NO2 is enhanced. Gas responses resulted to be influenced by the Mo/W weight ratio, films morphology and amount of crystalline phases.
