Abstract Aqueous zinc‐ion batteries (AZIBs), recognized for their safety and environmental friendliness, hold significant promise large‐scale energy storage. However, the rapid capacity degradation resulting from dissolution of active cathode materials hampers advancement AZIBs. Here, Ru 0.2 V 2 O 5 ∙0.41H (RuVO) is synthesized with remarkable retention (98.2% over 5000 cycles at 10 A g −1 ). The pre‐intercalation 3+ enhances stability both intrinsic cycling structures, elevating Gibbs free suppressing V‐dissolution thermodynamically. Additionally, intercalation modulates potential surface Zn 2+ migration, leading to dominance in insertion/extraction mechanism, thereby kinetically impeding reaction. This study elucidates thermodynamics kinetics V‐based cathodes through a combination experiments, mechanism analyses, density functional theory (DFT) calculations.

Atomic-level Ru-Ir mixing in rutile-type (RuIr)O2 for efficient and durable oxygen evolution catalysis

Nature Communications, Год журнала: 2025, Номер 16(1)

Abstract The success of proton exchange membrane water electrolysis (PEMWE) depends on active and robust electrocatalysts to facilitate oxygen evolution reaction (OER). Heteroatom-doped-RuO x has emerged as a promising because heteroatoms suppress lattice participation in the OER, thereby preventing destabilization surface Ru catalyst degradation. However, identifying suitable achieving their atomic-scale coupling with atoms are nontrivial tasks. Herein, steer pathway away from involvement oxygen, we integrate OER-active Ir into RuO 2 matrix, which maximizes synergy between stable centers, by leveraging changeable growth behavior Ru/Ir parameter-modulated templates. In PEMWE, resulting (RuIr)O /C demonstrate notable current density 4.96 A cm −2 mass activity 19.84 mg Ru+Ir −1 at 2.0 V. situ spectroscopic analysis computational calculations highlight importance synergistic coexistence Ru/Ir-dual-OER-active sites for mitigating dissolution via optimization binding energy intermediates stabilization sites.
