Abstract
AbstractIt is extremely difficult to distinguish the contributions of different sites on the surface and in the inner sites of a catalyst to the overall catalytic performance, as the observed catalytic results reflect an ensemble average from almost all the active sites. How do the inner sites of a catalyst that seem to be not directly involved in a catalytic process exactly contribute to the catalytic performance? Toward this goal, herein the studies not only provide fundamental insights into how the alteration of Au8n+4(SR)4n+8 clusters by only the inner structure can dramatically change the intrinsic catalytic properties, where Au8n+4(SR)4n+8 (n = 3, 4, 5) clusters have the same surface motifs but share a periodic kernel structure, but also further demonstrate that the evolution in catalytic activity can potentially be determined by periodic transformation in the inner kernels.
