Efficient electrocatalysts composed of non‐precious elements are central to the development of overall water‐splitting system. Herein, it is demonstrated that 2D CoNi‐metal‐organic framework (CoNi‐MOF) array grown directly on a Cu substrate is a highly efficient and stable electrocatalyst for oxygen evolution reaction with a low overpotential (265 mV at 10 mA cm−2) in alkaline medium. With the combination of in situ conducting atomic force microscopy and two‐point conductivity measurements, it…
