Abstract

A facile chemical method to prepare a Pt layer selectively on Au nanoparticles is developed. The hydrogen presorbed into Au nanoparticles during NaBH₄ treatment leads to the formation of a thin Pt layer on Au nanoparticles. The Pt-coated Au nanoparticles exhibit significantly improved electrocatalytic activity for the electrooxidation of formic acid.
