Developpement of cobalt-based active phase for the detection of methane and carbon dioxide

Abstract

Tin oxide is widely used in the fabrication of catalytic gas sensor, due to its capacity to generate an electronic signal easy to measure, and its high resistance to poisonning and aging. However, all the experiments performed showed clearly the total absence of interaction between our chosen active phase and the two target gases. This could be explained by the fact that tin oxide is exclusively used with doping material such as platinum, palladium or gold. It could also explain why tin oxide sensor have such a high resistance to poisonning. However, it means that, before any sensor prototype could be built using tin oxide, an important study will be required, in order to determine which doping material is the most promising, and the amount needed to acquire a good interaction with the target gasesinfo:eu-repo/semantics/nonPublishe
