Atomically precise Au n nanoclusters (n= number of gold atom in cluster) ideally composed of an exact number of gold atoms have unique core–shell structure and non-metallic electronic properties. The extremely small size of Au25 and Au38 nanoclusters induces a large energy gap in their electronic structures, which gives rise to unprecedented catalytic activity in some chemical reactions. Here we report dehydration of phenylboronic acid to ...
