Colloidal Phase Control of Ni-P Nanocrystals Reveal a P-Site Hydrogen Evolution Reaction Mechanism Distinct from Ni-Rich Analogues

Nickel phosphides have emerged as promising earth-abundant catalysts for the hydrogen evolution reaction (HER), yet most studies have focused on Ni-rich phases (e.g., Ni 2 P, Ni 5 P 4 ), where catalytic activity is commonly...
