摘要：

It is highly needed but still a difficult challenge to achieve energy-saving electrolytic hydrogen generation. In this communication, we describe the first use of iron phosphide nanosheets array on Ni foam as a high-active and durable catalyst for electrochemical hydrazine oxidation reaction (HzOR) in alkaline media. The high hydrogen-evolving activity of this catalyst electrode and the substitution of sluggish oxygen evolution with thermodynamically more favorable HzOR enables the construction of a stable two-electrode energy-efficient electrolytic hydrogen generation system capable of driving 125mA cm(-2) at a cell voltage of 0.5V to in 1.0M KOH with 0.5M hydrazine.
