Study of influence of palladium additives in nanosized tin dioxide on sensitivity of adsorption semiconductor sensors to hydrogen

a b s t r a c t Nanosized materials based on tin dioxide with palladium additives were synthesized to produce gas sen- sitive layers of the adsorption semiconductor hydrogen sensors. The synthesis of nanosized Pd-containing materials based on SnO2 was carried out by a sol-gel method using ethylene glycol as a solvent. Influence of palladium additives on sensitivities of the sensors to H2 and catalytic properties of the corresponding Pd-containing sensor materials in reaction of H2 oxidation were studied. It was shown that the sen- sor properties depended on catalytic processes of H2 oxidation on the sensor surfaces. The most active hydrogen sensor contains only 0.016 wt% Pd and at its optimal operating temperature demonstrates a fast response time (3 s) and quick recovery time (7 s) comparatively to reported earlier hydrogen sensors. The proposed fast-acting sensors are capable to measure hydrogen in a wide range of its concentrations (6-800 ppm H2) at relatively low operating temperatures. © 2014 Elsevier B.V.
