Facile Synthesis Of Continuous Pt Island Networks And Their Electrochemical Properties For Methanol Electrooxidation

摘要

A two-dimensional continuous Pt island network was successfully synthesized by pulse-potentiostatic electrodeposition on a flat silicon substrate, which showed markedly enhanced catalytic activity toward methanol electrooxidation and high CO tolerance, probably due to the synergistic effect of the Pt island catalyst and surrounding SiO_2 surface layer.rnOver the past few years, synthesis of nanostructured materials has received great interest in the technology due to its wide range of applications in biosensors, energy system, catalysis, and in self-assembly of supramolecular structures.
