| Abstract: | Improving the activity and reducing the amount of supported precious metals play an important role in the research of electrocatalysts for proton exchange membrane fuel cells (PEMFCs). Platinum (Pt) based nanomaterials are one of the key parts of enhancing the activity of the cathode catalysts on oxygen reduction reaction (ORR). Based on the analysis of 104 published papers, the influences of particle size, crystal facets and morphologies of the Pt-based nanoparticles (NPs) on the activity and stability of catalysts, as well as the alloy compositions and the core-shell structure on the catalytic performance, are discussed. By analyzing the advantages and shortcomings of the existing methods and technologies, and the research directions of designing catalysts with ordered nanostructure and optimizing the ORR process are proposed. |
