Tailored Lattice Compressive Strain of Pt‐Skins by the L12‐Pt3M Intermetallic Core for Highly Efficient Oxygen Reduction

The sluggish kinetics of oxygen reduction reaction (ORR) and unsatisfactory durability of Pt‐based catalysts are severely hindering the commercialization of proton‐exchange‐membrane fuel cells (PEMFCs). In this work, the lattice compressive strain of Pt‐skins imposed by Pt‐based intermetallic cores...

Description
Summary:The sluggish kinetics of oxygen reduction reaction (ORR) and unsatisfactory durability of Pt‐based catalysts are severely hindering the commercialization of proton‐exchange‐membrane fuel cells (PEMFCs). In this work, the lattice compressive strain of Pt‐skins imposed by Pt‐based intermetallic cores is tailored for highly effective ORR through the confinement effect of the activated nitrogen‐doped porous carbon (a‐NPC). The modulated pores of a‐NPC not only promote Pt‐based intermetallics with ultrasmall size (average size of
