Non-metal-hybridized platinum-based compositionally complex alloys for efficient oxygen reduction reaction in fuel cells (opens in new tab)

Incorporating light non-metallic elements into compositionally complex alloy (CCA) electrocatalysts can potentially overcome the activity–stability trade-off challenge. However, practical realization of this potential is limited by the lack of a generic method to incorporate multiple types of non-metal into single-phase CCAs. Here we present a facile solvothermal strategy enabling the incorporation of fluorine, boron and nitrogen into the interstitial sites of Pt-based CCAs. Mechanistic inves...
