摘 要：1.Introduction In recent decade,atomically precise metal nanoclusters,comprised of metal kernel and surface protecting ligands,have appeared as a new and promising nanomaterial for abundant applications,such as nanocatalysis,sensor,photoluminescence,a few to name,which is attributed to their electron energy quantization arising from quantum size effect[1].And the very recent investigations showed that the configuration of metal kernel and the electronic properties of metal nanoclusters with the same metal core are largely affected by the surface protecting ligands[[2],[3]].For example,the surface ligands can significantly alter the catalytic performance of metal nanocluster catalysts(e.***.activity and selectivity)in a positive way.We have found that the Au_(25)(SR)_(18)nanocluster with the aromatic ligands can give higher conversions and a markedly increasing selectivity toward the desired product[4].
