NiFe layered double hydroxide (NiFe LDH) is a promising material with multiple functions. In this communication, a novel method is used to prepare NiFe LDH. This synthesis method is achieved galvanic-cell corrosion between nickel and iron substrates in aqueous solutions containing a halogen group anion (, Cl) at ambient temperature. The as-prepared NiFe LDH electrodes are developed as electrocatalysts for the oxygen evolution reaction (OER) and exhibit excellent catalytic activities and durability. This work provides an energy-efficient, cost-effective, and scaled-up corrosion engineering approach for manufacturing NiFe LDH materials.
镍铁层状双氢氧化物（NiFe LDH）是一种具有多种功能的有前途的材料。在本通讯中，采用了一种新颖的方法来制备NiFe LDH。这种合成方法是通过在室温下，在含有卤素基团阴离子（如Cl）的水溶液中，镍和铁基底之间发生原电池腐蚀来实现的。所制备的NiFe LDH电极被开发用作析氧反应（OER）的电催化剂，并表现出优异的催化活性和耐久性。这项工作为制造NiFe LDH材料提供了一种节能、经济高效且可扩大规模的腐蚀工程方法。
