资源简介：

This proposal aims to investigate the Strong Metal-Support Interaction between Cu catalysts of sizes varying from single-atoms to nanoparticles and Co3O4 supports in metal oxide-based gas sensors. While metal catalysts are known to improve sensor selectivity, the mechanisms behind this enhancement remain unclear. By using Extended X-ray Absorption Fine Structure at the Cu and Co K-edges, we will analyze how catalyst size influences SMSI, the reducibility of Co₃O₄, and oxygen vacancy formation under different gas environments. The results will advance the understanding of SMSI, providing key insights for designing more selective gas sensors.
