Article Synopsis
- * A new strategy is introduced to create oxygen-deficient Ni-Mo-Fe structures in NiFe (oxy)hydroxide that improve reaction kinetics by lowering energy barriers in key steps of the HER.
- * The enhanced catalyst, NFM-OV/NF, shows exceptional performance with low overpotentials and impressive long-term stability, making it a cost-effective option for producing hydrogen, achieving a price of $0.92 per gallon equivalent, which is below 2026 energy targets.
As promising oxygen evolution reaction (OER) catalysts, spinel-type oxides face the bottleneck of weak adsorption for oxygen-containing intermediates, so it is challenging to make a further breakthrough in remarkably lowering the OER overpotential. In this study, a novel strategy is proposed to substantially enhance the OER activity of spinel oxides based on amorphous/crystalline phases mixed spinel FeNiO nanosheets array, enriched with oxygen vacancies, in situ grown on a nickel foam (NF). This unique architecture is achieved through a one-step millisecond laser direct writing method.
