Architecture Evolution of Different Nanoparticles Types: Relationship between the Structure and Functional Properties of Catalysts for PEMFC

This review considers the features of catalysts with different nanoparticle structures architecture transformation under various pre-treatment types. Based on results publications analysis, it can be concluded that chemical or electrochemical activation bimetallic has a significant effect their composition, microstructure, and catalytic activity in oxygen reduction reaction. The stage is recommended for use as mandatory catalyst to obtain highly active de-alloyed materials. literature studied, which covers possible variants structural modification influence thermal treatment processing conditions. Additionally, based data recommendations are given alloyed d-metals.
