Abstract Entropy‐based polymetallic oxides with configurational entropy, structure flexibility, and crystallographic orientation have been regarded as promising catalysts for oxygen evolution reaction (OER), due to their electronic energy band occupation, composition ligand stabilization, “cocktail” effect. Herein, a rutile RuIrAgMnO 2 oxide an along the (110) facets is first fabricated by low‐temperature directional co‐pyrolysis strategy of metal salts on Ti foil at 300 °C. The quaternary exhibits texture coefficient 1.13 facet, resulting from concerted shaping Ag Mn components presenting vibrational entropy R (R gas content). In 0.5 m H SO 4 , it displays overpotential 171 mV 10 mA cm −2 OER, running voltage 340 h 100 . remarkably improved performance can be associated presence preferred in‐plane strains, which activate stabilize OER process via reconstruction. More interestingly, preferential prevents diffusion or dissolution active ions caused entropy‐dependent barriers, ensuring long‐term stability. This work pave way entropy‐driven optimal structures, disrupting trade‐off between activity stability in water oxidation.

Abstract Metal‐air secondary batteries with ultrahigh specific energies have received vast attention and are considered new promising energy storage. The slow redox reactions between oxygen‐water molecules lead to low efficiency (55–71%) limited applications. Herein, it is proposed that the MIL‐68(In)‐derived porous carbon nanotube supports CoNiFeP heteroconjugated alloy catalyst an overboiling point electrolyte achieve oxidation rate of water molecules. Structural characterization density functional theory calculations reveal greatly reduces free process, further accelerates dissociation O─H hydrogen bonds, release O 2 molecules, achieving extra‐low overpotential 110 mV@10 mA cm −2 far lower than commercial Ir/C catalysts 192 mV at 125 °C state‐of‐the‐art. Furthermore, assembled rechargeable zinc‐air begins break through 85 °C, jumps 100 reaches 88.1% ultralow decay 0.0068% after 150 cycles superior those reported metal‐air batteries. This work provides a joint‐design strategy reexamines battery operating temperature construct higher for fuel cells.
