- Abstract
Nanosized materials based on tin dioxide with palladium additives obtained by sol-gel method using ethylene glycol have been synthesized for producing a gas sensitive layer of adsorption-semiconductor sensors toward hydrogen. The influence of low concentrations of palladium on the sensor characteristics to 40 ppm H2 has been studied. It has been shown that the properties of Pd-containing sensors are defined by catalytic processes of H2 oxidation running on the sensor surfaces.
