Abstract
Abstract By providing dual active sites to synergistically accelerate H 2 O dissociation and H + reduction, ordered intermetallic alloys usually show extraordinary performance for pH‐universal hydrogen evolution reaction (HER). Herein, activated N‐doped mesoporous carbon spheres supported intermetallic Pt 3 Fe alloys (Pt 3 Fe/NMCS‐A), as a highly‐efficient electrocatalyst for pH‐universal HER, are reported. The Pt 3 Fe/NMCS‐A exhibits low overpotentials ( η 10 ) of 13, 29, and 48 mV to deliver 10 mA cm −2 in 0.5 m H 2 SO 4 , 1.0 m KOH, and 1.0 m phosphate buffered solution (PBS), respectively, as well as robust stability to maintain the overall catalytic performances. Theoretical studies reveal that the strong…
