Mn‐Induced Support Stabilization and Ir Electronic Activation Enable Acid‐Stable, Low‐Loading IrO2 Water Oxidation

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
This study introduces a dual‐regulation strategy utilizing a Mn‐doped Co3O4 support to enhance the activity and stability of low‐loading IrO2 catalysts for acidic water oxidation. Mn induces strong Mn─O covalency to reinforce the spinel lattice and activates Ir sites via interfacial electron transfer.

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

open access: yesAdvanced Energy Materials, Volume 16, Issue 29, 5 August 2026.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Ni–Cr Substitution in TiFe: An Integrated Experimental–Modeling Study of Phase Stability and Hydride Thermodynamics

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Combined experimental and theoretical approaches reveal how Cr and Ni substitution in TiFe‐based alloys tune lattice expansion and hydride thermodynamics. While both elements increase hydride stability, they exert opposite effects on the entropy of hydrogen desorption, providing new insight into thermodynamic design of AB‐type hydrogen storage ...
