Electrons and Hydroxyl Radicals Synergistically Boost the Catalytic Hydrogen Evolution from Ammonia Borane over Single Nickel Phosphides under Visible Light Irradiation

From the perspective of tailoring the reaction pathways of photogenerated charge carriers and intermediates to remarkably enhance the solar‐to‐hydrogen energy conversion efficiency, we synthesized the three low‐cost semiconducting nickel phosphides Ni 2 P, Ni 12 P 5 and Ni 3 P, which singly catalyzed the hydrogen evolution from ammonia borane (NH 3 BH 3 ) in the alkaline aqueous solution under visible light irradiation at 298 K. The systematic...
