Platinum-Containing Adsorption-semiconductor Sensors Based on Nanosized Tin Dioxide for Methane Detection

It was found that platinum-containing adsorption-semiconductor sensors based on nanosized tin dioxide obtained by the sol–gel technique have higher sensitivity to CH 4 than analogs known in literature. The sensitivity of the sensors to methane depends on the platinum content of their gas-sensitive l...

Description
Summary:It was found that platinum-containing adsorption-semiconductor sensors based on nanosized tin dioxide obtained by the sol–gel technique have higher sensitivity to CH 4 than analogs known in literature. The sensitivity of the sensors to methane depends on the platinum content of their gas-sensitive layer, and this is explained by influence of the CH 4 heterogeneous catalytic oxidation that occurs on the surface of the sensors.
