Sensitivity to hydrogen of sensor materials based on SnO2 promoted with 3d metals

Theoretical and Experimental Chemistry Aims and scope

Abstract

The sensitivity to hydrogen and the catalytic activity in the oxidation of hydrogen of sensor materials based on tin dioxide and doped with cobalt, nickel, iron, and copper have been studied. The sensitivity of the sensors and the degree of conversion of hydrogen pass symbatically through a maximum with increasing quantity of each of the dopants. The results are explained by the influence of grain boundaries between tin dioxide and the dopants applied during the course of the oxidation reaction of hydrogen on the sensor material and on the sensitivity of the sensor to H2.
