Developing earth-abundant and high-performance electrocatalysts toward the alkaline hydrogen evolution reaction ( HER) is highly desired. In this communication, we report a Mn-doped Ni2P nanosheet array on nickel foam (Mn-Ni2P/NF) as a high-efficiency electrocatalyst for the HER in alkaline solutions. This Mn-Ni2P/NF can drive 20 mA cm(-2) at an overpotential of 103 mV in 1.0 M KOH, which is 82 mV less than that for Ni2P/NF. In addition, it also demonstrates excellent long-term electrochemical durability for at least 25 h. This work offers us a promising catalyst material for water-splitting devices for large-scale production of hydrogen fuels.
