摘要：
In this communication, we report on the first use of Ni3Se2 film electrochemically deposited on Cu foam (Ni3Se2/CF) as a bifunctional catalyst for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) with good durability at alkaline media. This 3D electrode exhibits high activity of 10 mA cm(-2) at 100 mV HER overpotential and 50 mA cm(-2) at 340 mV OER overpotential. A Ni3Se2/CF-based two-electrode alkaline water splitting system affording 10 mA cm(-2) at a cell voltage of 1.65 V is also demonstrated successfully.
