Non-metal-hybridized platinum-based compositionally complex alloys for efficient oxygen reduction reaction in fuel cells

Nature Catalysis, Published online: 22 May 2026; doi:10.1038/s41929-026-01544-5 Pt-based alloys are among the most active catalysts for fuel cells, but strategies to improve their performance are still needed. Now a series of non-metal-modified Pt-based compositionally complex alloys is prepared via a general solvothermal approach and tested for the oxygen reduction reaction, where PtCuNiCoN is shown to exhibit excellent performance.
