Abstract Polymetallic oxides with extraordinary electrons/geometry structure ensembles, trimmed electron bands, and way‐out coordination environments, built by an isomorphic substitution strategy, may create unique contributing to concertedly catalyze water oxidation, which is of great significance for proton exchange membrane electrolysis (PEMWE). Herein, well‐defined rutile InSnRuO 2 density‐controllable oxygen vacancy (Ov)‐free polarons are firstly fabricated in situ substitution, using trivalent In species as Ov generators the adjacent metal ions donors form orderly concerted In‐Ov‐Ru‐O‐Sn substructures tetravalent oxides. For acidic obtained displays ultralow overpotential 183 mV (versus RHE) a mass activity (MA) 103.02 A mg Ru −1 , respectively. long‐term stability test PEMWE, it can run at low unchangeable cell potential (1.56 V) 200 h 50 mA cm −2 far exceeding current IrO ||Pt/C assembly 0.5 m H SO 4 .
