Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

Carbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.

Surface Reconstruction‐Promoted Alkaline Overall Water Splitting on Fe‐Doped Ni2P/NiMoO4 Composite Structure

Electron, EarlyView.
Fe‐Ni2P/NiMoO4 heterostructure delivers bifunctional performance for both HER and OER in alkaline solution. During OER, Fe doping suppresses LOM through electronic modulation, which consequently leads to an AEM route with enhanced OH* adsorption. Furthermore, the elimination of oxygen‐loss pathways ensures the structural integrity of the Fe‐Ni2P ...

Judging by the Rules? The emergence of evaluation practices

Valuation Studies
How does evaluation work differently, and how do evaluation practices emerge, in different contexts? Drawing on a mixed-methods study of evaluation in figure skating and classical music, I discuss the divergent evaluative cultures in these settings ...
