Time Scale and Elementary Steps of CO‐Induced Disintegration of Surface Rhodium Clusters

Abstract

The disintegration of Rh clusters on an Al2O3 surface induced by CO, the elementary steps, and timescale of the reaction are analyzed for the first time by energy-dispersive X-ray absorption fine structure (DXAFS) at a time resolution of 100 ms (see picture). This study by the improved time-resolved DXAFS technique provides a new research area of structural dynamics of catalytically active materials at surfaces.
