Uniform Pd–Pt alloy nanoparticles supported on graphite nanoplatelets with high electrocatalytic activity towards methanol oxidation

Abstract

Uniformly dispersed Pd–Pt alloy catalysts with different Pt/Pd ratios on 1-pyrenecarboxylic acid (PCA) modified graphite nanoplatelets (GNPs) were obtained using a one-pot approach. The binary composition of these Pd–Pt/GNPs catalysts can be controlled by simply adjusting the molar ratio of the Pd and Pt precursors.
