Non-noble-metal electrode materials with high durability and efficiency have become the frontiers of energy conversion and storage fields. However, conventional electrode materials often show high overpotential and low conductivity. To solve this problem, we fabricate a NiMo_xCo_2−x layered double hydroxide (LDH)/Ni foam (NF) product through a facile hydrothermal route. The as-prepared NiMo-Co-LDH/NF catalyst possesses an overpotential of 123 mV for hydrogen evolution reaction (HER) at 10 mA cm⁻² and 279 mV for oxygen evolution reaction (OER) at 20 mA cm⁻². The as obtained product exhibits excellent overall water splitting performances. Meanwhile, as the electrode material for supercapacitor, it delivers high specific capacitance and excellent cyclic performance. The asymmetric supercapacitor assembled with NiMoCo-LDH/NF//active carbon exhibits 93% of its initial capacity after 8000 cycles.

具有高耐久性和效率的非贵金属电极材料已经成为能量转换和存储领域的前沿。然而，常规电极材料通常显示出高的过电势和低的电导率。为了解决这个问题，我们通过一条便捷的水热路线制造了NiMo _x Co _{2- x}层状双氢氧化物（LDH）/ Ni泡沫（NF）产品。所制备的NiMo-Co-LDH / NF催化剂在10 mA cm ^-2时对于氢析出反应（HER）具有123 mV的过电势，而在20 mA cm ^-2下对于氧析出反应（OER）具有279 mV的过电势。。所获得的产品表现出优异的整体水分解性能。同时，作为超级电容器的电极材料，它具有高的比电容和出色的循环性能。用NiMoCo-LDH / NF //活性炭组装的不对称超级电容器在8000次循环后展现出其初始容量的93％。
