Abstract
Highly ordered PtM intermetallic alloy structures are proven effective to improve their catalytic activity and stability for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells. Here, we discuss our recent progress to prepare ordered PtCo intermetallic nanoparticles derived from atomically metal site-doped metal–organic-framework (MOF). In particular, the atomically dispersed Co sites, which are originally embedded into MOF-derived carbon, diffuse into Pt nanocrystals and form ordered Pt3Co structures. It is very crucial for the formation of the ordered Pt3Co to carefully control the doping content of Co into the MOFs and the heating temperatures for Co diffusion. In this presentation, detailed catalyst synthesis, extensive characterization, and comprehensive RDE tests and fuel cell evaluation will be discussed.
