Abstract

D-band engineering via alloying platinum is a leading design principle for advanced oxygen reduction electrocatalysts, but stability remains a concern. Here the authors make Pt nanoparticles supported on graphite-rich boron carbide for enhanced activity and stability, isolating and optimizing the electronic metal-support interactions.
