Ordered Pt3Mn Intermetallic Nanoparticles Supported on Atomically Dispersed Mn–N–C as Electrocatalysts for Fuel Cells

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
Ordered L12‐Pt3Mn intermetallic alloys are uniformly deposited onto atomically dispersed Mn–N–C supports. The synergistic effect between MnN4 sites and Pt3Mn elevates interfacial binding strength and dissolution barriers while favorably weakening *OH adsorption. It delivers exceptional catalytic activity and stability in fuel cells, serving as an ideal
