Abstract

An ionic liquid (IL) solvent was used to synthesize small, phase-pure nickel phosphide (Ni 2 P) nanocrystals. In contrast, under analogous reaction conditions, substitution of the IL for the common high-boiling organic solvent 1-octadecene (ODE) results in phase-impure nanocrystals. The 5 nm Ni 2 P nanocrystals prepared in IL were electrocatalytically active toward the hydrogen evolution reaction. The synthesis in IL was also extended to alloyed Ni 2-x Co x P nanocrystals, where 0.5 ≤ x ≤ 1.5.
