Deep Eutectic Solvent-Assisted Electrodeposition of Dendritic FeCoNiCu Medium-Entropy Alloy for Efficient Alkaline Oxygen Evolution
Developing low-cost and durable non-noble-metal electrocatalysts for the oxygen evolution reaction (OER) is essential for efficient alkaline water electrolysis. Herein, FeCoNiCu medium-entropy alloy electrodes with tunable dendritic architectures were prepared on Cu substrates by one-step potentiostatic electrodeposi...
