Surface structure effects of platinum-based catalysts for oxygen reduction reaction

The structural sensitivity is one of the major themes in electrocatalysis, and it is now well established that the reaction rate of oxygen reduction reaction (ORR) on Pt-based catalysts depends strongly on the surface structure. This paper presents a brief overview of insights of surface structure effects of Pt-based catalysts for ORR. We first introduce some typical extended Pt-based surface and then focus on Pt-based nanoparticles in both ORR activity and stability.
