▎ 摘 要
Development of efficient and durable electrocatalysts for the oxygen evolution reaction (OER) is essential for sustainable hydrogen production by water splitting. The physicochemical properties of the electrocatalyst can be tailored by defect engineering. Herein, we report the fabrication of [Fe(CN)(6)](3-) coordination sphere vacancies via the rapid coprecipitation in Ni-3(II)[F-eIII (CN)(6)](2-x) (x ]]
