Abstract

The article discusses a wide range of issues related to the relationship between the composition and fine structure (architecture) of bimetallic nanoparticles and electrochemical performance of Pt-M/C (M = Cu, Co, Ni) electrocatalysts. Among these questions are: evolution of nanoparticles during thermo-treatment, catalytic activity in the oxygen reduction and methanol electro-oxidation reactions, corrosion-morphological stability of the catalysts, selective dissolution of alloying component.
