Abstract
- The support is pivotal for stabilizing single metal atoms and contributes to enhance the catalytic activity of single-atom catalysts. With the merits of versatile structures, tailored electronic structure, as well as high stability, manganese oxide octahedral molecular sieve (OMS-2) can be used as an ideal support to immobilize single atoms. Herein, we report a single-atom Pd catalyst (Pd<subscript>1</subscript>–OMS-2) that can afford a silane conversion of above 99% with silanol selectivity of over 99% using water as oxidant under mild conditions, outperforming the original OMS-2. The as-synthesized catalyst exhibits great functional group tolerance and good catalyst stability without aggregation after reaction. And the enhanced catalytic activity is attributed to the decoration of atomic Pd and the increase in content of oxygen vacancies. Characterization of Pd<subscript>1</subscript>–OMS-2 indicates that the highly dispersed Pd species is trapped into the framework of OMS-2 by substituting Mn ions, which results in the formation of Pd–O bonds with the adjacent O atoms.
