Abstract

A sustainable approach utilizing a low-temperature molten salt strategy is employed in this study to fabricate homogeneous and dense NiFe nitrate hydroxide needle-like arrays on a NiFe foam substrate. The electrode also achieves an ultra-low voltage of 1.77 V at 100 mA cm−2 and maintains stability for more than 120 h at a current density of 100 mA cm−2, showing excellent overall water splitting (OWS) performance and stability. Notably, the molten salt strategy enables the synthesis of electrodes at a reaction temperature as low as 125 °C. Additionally, the molten salt precursor is repeatable and renewable, thus preventing waste and presenting vast potential for application.

可重复和可再生的水电解用硝酸氢氧化镍铁针状阵列的合成。
本研究采用了一种可持续的方法,利用低温熔盐策略在NiFe泡沫衬底上制备均匀致密的NiFe硝酸氢氧化物针状阵列。该电极在100 mA cm-2电流密度下可实现1.77 V的超低电压,并在100 mA cm-2电流密度下保持120 h以上的稳定性,表现出优异的整体水分解(OWS)性能和稳定性。值得注意的是,熔盐策略可以在低至125°C的反应温度下合成电极。此外,熔盐前驱体可重复使用和可再生,从而防止浪费,具有巨大的应用潜力。
