The need for energy is rising quickly, and the usage of fossil fuels is contributing to the greenhouse effect and environmental pollution, both of which are raising public concerns. The development of novel electrochemical energy storage techniques as well as the creation of cleaner, more sustainable energies have both become highly researched topics as a result of this condition. New functional materials are being investigated for the advancement of energy storage. High entropy hydroxides (HEH) have lately been emerged as promising electrocatalyst for universal water splitting reactions, which are central for solid oxide fuel cells, hydrogen production and metal-air batteries. In this work, a cost-effective and scalable fabrication method was applied to fabricate several HEH on Nickel foam through single-step electrodeposition technique. Results showed that high-entropy FeCoNiMnOOH exhibits excellent OER activity with a low overpotential of 151 mV at current density of 100 mA cm−2, which is associated with it’s defective structure.
