WebOxygen Evolution Reaction (OER) OER is a crucial process in energy conversion and storage, especially in water electrolysis. Currently, precious metals and their oxide materials (Ir, Ru, IrO 2, and RuO 2 ), as state-of-the-art catalysts, are widely used in the OER process to reduce energy consumption and enhance energy conversion efficiency [90]. WebJun 1, 2024 · Recently, great efforts have been directed in searching for electrocatalysts for the oxygen evolution reaction (OER). In this work, a series of earth-abundant and low-cost iron-copper oxalates and oxides with varying iron/copper ratios were prepared and further examined as OER electrocatalysts.
WebNickel-iron based hydr(oxy)oxides have been well recognized as one of the best oxygen-evolving catalysts in alkaline water electrolysis. A crucial problem, however, is that iron leakage during prolonged operation would lead to the oxygen evolution reaction (OER) deactivation over time, especially under large current densities.
