Palladium-containing materials based on antimony-doped tin dioxide have been developed for gas-sensitive semiconductor sensors, showing significant response to CO, H-2, and light hydrocarbons. The sensor response value for each gas is highly dependent on the palladium content, with the optimal operating temperature determined by the reactivity of the gases being studied.
Palladium-containing materials based on antimony-doped tin dioxide have been developed to create a gas-sensitive layer of semiconductor sensors on a number of small molecules. Their catalytic activity in the CH4, CO, and H-2 oxidation reactions performed according to the Eley-Rideal mechanism has been studied. The sensors based on the obtained materials show a significant response to CO, H-2, and light hydrocarbons (CH4, C2H6, C2H2), while the dependence of the sensor response value of each of these gases on the palladium content is extreme. It is established that the optimal operating temperature of the sensor, which corresponds to the maximum of its response, is determined by the reactivity of the studied gases.
