title: FeP and FeP2 nanowires for efficient electrocatalytic hydrogen evolution reaction.
abstract: We report achieving of efficient electrocatalytic hydrogen evolution reaction using composition-controlled iron phosphide (FeP and FeP2) nanowires. The respective Tafel slopes of nanowire arrays were 39 and 37 mV dec(-1) in 0.5 M H2SO4, and 75 and 67 mV dec(-1) in 1 M KOH. The richer P composition produced excellent electrocatalytic efficiency.
