The development of renewable energy sources has recently drawn an increasing amount of attention as a means of addressing the global problems of environmental pollution and rising energy consumption[1]. Among the many options, hydrogen energy shows itself to be a strong contender as a clean and carbon-neutral energy source. Widely accepted as the best approaches to the hydrogen evolution reaction (HER), where electrical energy is used to directly split water, are electrochemical and photoelectrochemical water splitting[2]. The oxygen evolution reaction (OER), which involves a sequential proton-coupled electron transfer step and is more complex than the straightforward two-electron transfer process for HER, has relatively low kinetic rates and continues to be a significant barrier to the advancement of water splitting applications[3]. It is urgently necessary to create highly active electrocatalysts in order to reduce overpotentials and speed up reaction rates[4]. In this study, three metallic CoNiCu are successfully synthesized via the thermal annealing by doping Cu to MOF based NiCo as reported by
