Abstract High entropy metal oxides (HEO) are superior to many reactions involving multi‐step elementary reactions. However, controlled synthesis of hollow‐structured HEO catalysts, which offers large surface area and fast mass transfer kinetics, remains challenging unexplored due the complicated precursors. Herein, a organic framework‐templated polyhedron‐shaped catalysts assembled with ultra‐small nanoparticles, up ten elements, can be achieved, by taking advantage ion‐exchange method. ZnFeNiCuCoRu‐O catalyst displays excellent activity ultra‐stability for oxygen evolution reaction in full pH range, an overpotential 170 mV at current density 10 mA cm −2 , Tafel slope 56 dec −1 decay 7% 30 h alkaline medium, as well 12% 8% acidic neutral respectively. DFT calculation indicates that energy barrier potential determining step on Ru‐Fe bridge site is significantly lower than any other Ru‐related sites unique hollow structured structures. This work highlights importance method preparing highly stable active HEOs toward efficient conversion storage devices.
