The Pt SAC exhibited much better H 2 spill-over and hydrocarbon oxidation abilities with lower adsorption and dissociation energies than the manganese oxide support because of its local electronic structure with less repulsion. The pre-stabilization of Pt by coordinated oxygen and the abundant surface defects of support are the determinants of high loading. Here, we reported a manganese oxide supported Pt SAC with a high loading of 5.6 wt.% synthesized by selective dissolution strategy. Furthermore, the decisive factors of loading maximum are still not clear. However, due to their high surface energy, noble metal single atoms like Pt tend to migrate and agglomerate to form larger clusters or nanoparticles, which makes it a challenge to fabricate noble metal SACs with high loading (> 5 wt.%). Single atom catalysts (SACs) have become one of research focuses in heterogeneous catalysis for their effective utilization of active metal atoms and unique properties in various catalytic reactions.
