We report a stable gold-copper alloy nanocluster with high catalytic performance. The nanocluster exhibits high thermal stability and contains rich uncoordinated copper sites, which contribute to its extremely high catalytic activity in C-O coupling reactions. This finding is of great significance for understanding the underlying rationale of ligand-functionalized metal nanocatalysts.
Ligand-passivated metal nanoclusters with both high stability and catalytic activity have been pursued for a long time to shed light on the underlying rationale of ligand-functionalized metal nanocatalysts in chemical transformations. Nevertheless, these atomically precise nanocatalysts often exhibit low catalytic activity due to the extensive coverage of active sites. In this work, we report a robust gold-copper alloy nanocluster with 74 nuclei with high catalytic performance. The nanocluster with molecular composition of Au41Cu33(RS)(40)(MeCN) (RSH is 4-fluorothiophenol) has been obtained in a simple way. The cluster contains 34 free electrons, making it a superatom that exhibits high thermal stability as envisioned. Surprisingly, rich uncoordinated copper sites are present on the surface of the cluster, leading to its extremely high catalytic activity (up to 39 269 TON) in C-O coupling reactions with a broad substrate scope.
