High dispersion of platinum–ruthenium nanoparticles on the 3,4,9,10-perylene tetracarboxylic acid-functionalized carbon nanotubes for methanol electro-oxidation

Abstract

Due to lots of carboxyl groups introduced uniformly on the carbon nanotube (CNT) surface, platinum-ruthenium nanoparticles were highly dispersed on the 3,4,9,10-perylene tetracarboxylic acid-functionalized CNT surface and showed improved electrochemical properties for methanol electrooxidation.
