Herein, we propose a green strategy to recover valuable metals from spent LIBs and convert them into high\u2010performance OER catalysts.

The results demonstrate that MFCNC\u2010150 synthesized at 150\u2009\u00b0C exhibits a unique petal\u2010like stacked morphology, high specific surface area, and excellent hydrophilicity. Benefiting from the regulation of the electronic structure induced by the multi\u2010metal synergistic effect and interactions among multi\u2010metal active sites, MFCNC\u2010150 exhibits outstanding OER activity in 1\u2009M KOH electrolyte, with an overpotential of only 237\u2009mV at a current density of 10\u2009mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    , a Tafel slope of 56.35\u2009mV dec\n                    <jats:sup>\u22121<\/jats:sup>\n                    , and long\u2010term stability exceeding 120\u2009h.
