Synthesis and catalytic activity of crown jewel-structured (IrPd)/Au trimetallic nanoclusters

Crown jewel-structured (IrPd)/Au trimetallic nanoclusters are prepared by galvanic replacement reaction using Ir/Pd nanoclusters with a structure of Ir rich in core and Pd rich in shell as mother clusters. The catalytic activity of the top Au atoms for aerobic glucose oxidation of the trimetallic nanoclusters is the highest ever reported among all the supported and colloidal catalysts.
