Fabrication Strategies of Advanced Nanoelectrocatalysts for Fuel Cells
State Key Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, CAS
Abstract: As a type of promising clean energy source for the future, fuel cells have attracted increasing attention in recent years. However, the traditional Pt nanoparticles-based electrocatalysts for both anodic and cathodic reactions have obvious shortcomings, including high cost, slow reaction kinetics of ORR and CO or methanol poisoning during the fuel oxidation, which impede the wide commercialization of fuel cells. Therefore, designing and exploring novel nanomaterials, e.g. Pt-free or low-Pt electrocatalysts, with low loading of precious metals, high catalytic performance and high CO- or methanol-tolerance are of crucial importance for the development of fuel cells. In our recent studies, different strategies have been developed to synthesize nanoelectrocatalysts with improved catalytic activity and stability. Here, we highlight the metal@metal core@shell nanostructured materials with quasi-monolayer Pt skin or metal@carbon core@shell materials as advanced fuel cell electrocatalysts.
