![]() ![]() ![]() RHE to drive 1000 mA cm −2 and Tafel slopes of 31.2 and 11.9 mV dec −1, respectively, and a long durability of 120 h to achieve 100 mA cm −2. The fabricated Fe-NiCoZnP/NF catalyst displays outstanding HER and HzOR activity and durability, with potentials of 121 and 13 mV vs. The introduction of Fe can tune the electron structure of NiCoZnP/NF, leading to a modulation of the d-band center towards the Fermi level, hence optimizing the free energy of hydrogen (Δ G H*) and dehydrogenation behavior of hydrazine, and thereby realizing splendid HER and HzOR activities. Herein, a Fe-doped Ni 2P-Co 2P-Zn 3P 2 heterogeneous electrocatalyst with a nanoneedle-assembled nanosphere structure and abundant defects was fabricated on Ni foam (Fe-NiCoZnP/NF). Water-splitting coupled with the hydrazine oxidation reaction (HzOR) is a remarkably important strategy for H 2 production, but remains a challenge. ![]()
