Constructing efficient and low-cost oxygen evolution reaction (OER) catalysts operating in seawater is essential for green hydrogen production but remains a great challenge. In this study, we report an iron doped cobalt carbonate hydroxide nanowire array on nickel foam (Fe-CoCH/NF) as a high-efficiency OER electrocatalyst. In alkaline seawater, such Fe-CoCH/NF demands an overpotential of 387 mV to drive 500 mA cm, superior to that of CoCH/NF (597 mV). Moreover, it achieves excellent electrochemical and structural stability in alkaline seawater.
构建在海水中运行的高效低成本析氧反应（OER）催化剂对于绿色制氢至关重要，但仍然是一个巨大的挑战。在本研究中，我们报道了一种负载在泡沫镍上的铁掺杂氢氧化碳酸钴纳米线阵列（Fe-CoCH/NF）作为高效OER电催化剂。在碱性海水中，这种Fe-CoCH/NF驱动500 mA cm需要387 mV的过电位，优于CoCH/NF（597 mV）。此外，它在碱性海水中实现了优异的电化学和结构稳定性。
