Abstract
Abstract To date, a wide variety of mesoporous metals has been synthesized using self-assembly of polymeric micelles for catalytic and sensing applications. However, systematic study of trimetallic mesoporous alloys has rarely been performed due to their complex nature. Herein, we demonstrate the synthesis of mesoporous PdPtRh particles by a chemical reduction process with the assistance of a block copolymer, Pluronic® F127. Furthermore, we have also systematically characterized these alloys and evaluated their catalytic performance for methanol oxidation reaction (MOR), in comparison to mesoporous Pt and PdPt particles. Among all the prepared catalysts, the mesoporous PdPtRh sample shows the highest electrocatalytic performance for MOR with high conversion efficiency and tolerance for intermediate generation as well as excellent stability.
