Transition metal catalysts undergo dynamic surface reconstruction during the oxygen evolution reaction (OER), yet kinetic barriers inherently restrict the formation of high‐valent active species. Here, nanocone‐structured CoFeNi catalysts are designed to synergistically couple electric and magnetic...
