Electrochemical water splitting is a promising technology to produce hydrogen energy from water utilizing electricity. However, the sluggish kinetics of an oxygen evolution reaction (OER) hinder the achievement of high energy efficiency, acting as a barrier to the widespread adoption of electrolysis technology. Herein, we have developed CuxCoy(OH)₂ by incorporating Cu into Co(OH)₂. Furthermore, we systematically analyzed the structural and electrochemical characteristics based on the ratio of Cu to Co. Despite incorporating Cu into Co(OH)₂, the nanosheet shape was relatively well-preserved. Nevertheless, an excessive Cu content in CuxCoy(OH)₂ led to the transformation of nanosheets into polygonal shapes. Increasing Cu content improved OER activity, but excessive Cu diminished OER activity, resulting in changes in surface shape and crystal structure. This study highlights the significance of compositional optimization in developing binary hydroxide-based OER electrocatalysts.
