摘要：
Addition of cerium to sensor nanomaterials based on tin dioxide leads to a significant increase in their catalytic activity, which is a reason of increasing the sensitivity to H2 of obtained adsorption semiconductor sensors. Mechanism proposed for the surface heterogeneous catalytic hydrogen oxidation reaction includes both reactions involving chemisorbed oxygen at the interface between tin dioxide nanoparticles and introduced cerium dioxide and reactions involving CeO2.
