One-dimensional core-shell nanowire materials have recently received great attention as durable catalysts for water splitting. Herein we report the facile and rapid synthesis of ultralong Fe(OH):Cu(OH) core-shell nanowires grown in situ on an open 3D electrode to function as a highly efficient electrocatalyst for water oxidation. It only requires an overpotential of ∼365 mV to reach a 10 mA cm current density in 1.0 M KOH. As far as we know, this shows the best result amongst Cu-based heterogeneous OER systems reported to date.
一维核壳纳米线材料作为用于水分解的耐用催化剂，最近受到了极大关注。在此，我们报告了在开放的三维电极上原位生长的超长Fe(OH)₂:Cu(OH)₂核壳纳米线的简便快速合成方法，该纳米线可作为高效的水氧化电催化剂。在1.0 M KOH中，仅需约365 mV的过电位即可达到10 mA cm⁻²的电流密度。据我们所知，这是迄今为止报道的铜基非均相析氧反应（OER）体系中的最佳结果。
