Abstract
Developing oxygen evolution reaction (OER) catalysts with optimum composition and highly active catalytic centres is a challenge during electrode scale-up. We show a selection strategy for the optimum composition of Co-Fe-Ni catalyst systems through a scanning droplet cell-based high-throughput screening on thin-film materials libraries, followed by fabrication and testing of the selected compositions in the form of catalyst-coated porous electrodes for the OER in alkaline media. The electrode with optimum composition (Co17Fe25Ni58_Ni foam) exhibits a high current density of 1 A cm−2 during water electrolysis at an operating potential of ∼1.9 V.
开发具有最佳成分和高活性催化中心的析氧反应（OER）催化剂是电极放大过程中的一个挑战。我们通过基于扫描液滴细胞的薄膜材料库高通量筛选，展示了Co-Fe-Ni催化剂体系的最佳组成的选择策略，然后以碱性介质中OER的催化剂涂层多孔电极的形式制作和测试所选择的组合物。在工作电位为~ 1.9 V的电解过程中，具有最佳组成的电极（Co17Fe25Ni58_Ni泡沫）具有高达1 a cm−2的高电流密度。
