Very Low Temperature CO Oxidation over Atomically Precise Au₂₅ Nanoclusters on MnO₂.

ABSTRACT: Atomically precise Au₂₅ nanoclusters have garnered significant interest in the field of heterogeneous catalysis due to their remarkable activity and selectivity. However, for the extensively studied reaction of low-temperature CO oxidation, their performance has not been competitive compared to other known gold nanocatalysts. To address this, we deposited Au₂₅(SR)₁₈ (R = CH₂CH₂Ph) nanoclusters onto a manganese oxide support (Au₂₅/MnO₂), resulting in a very stable and highly active catalyst. By optimizing the pretreatment temperature, we were able to significantly enhance the performance of the Au₂₅/MnO₂ catalyst, which outperformed most other gold catalysts. Impressively, 100% conversion of C
