Abstract Metal‐organic framework (MOF)‐derived materials have been widely applied to diversified fields until now due their flexible processibility. Different kinds of suitable can be synthesized by varying MOF templates/precursors and synthesis methods. An appropriate method skillfully fabricate the with excellent performance while meeting environmentally friendly concept. In this work, a green grinding was introduced synthesize MOF‐derived FeNiCo trimetallic without solvent‐assistance, in which Co‐ZIF‐L selected as sacrificial precursor Fe 3+ Ni 2+ etchants dopants. Surprisingly, as‐prepared ternary hydroxides supported on foam (G‐FeNi‐Co‐ZIF‐L/NF) showed superior electrocatalytic for oxygen evolution reaction (OER) low overpotential 248 mV at 10 mA cm −2 . This work provides prospective approach various multi‐metallic materials, also opens door syntheses OER electrocatalysts.
