Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

Small, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...

Interplay Between Oxidation State, Intervalence Charge Transfer Transitions and Electronic Conductivity in a Series of Ru‐Based Metal–Organic Frameworks

Small, EarlyView.
Ru‐based square‐grid metal–organic frameworks undergo dramatic conductivity enhancements after chemical oxidation. The mixed‐valent states exhibit the highest conductivity values, which correlate with the appearance of intervalence charge transfer bands.

Cu+‐Driven Formate Selectivity in Oxidation‐State‐Dependent CO2 Reduction on Cu2O|Graphene

Small, EarlyView.
A Cu2O|graphene heterostructure enables interfacial electronic self‐regulation that stabilizes catalytically active Cu+ species under cathodic CO2 reduction conditions. Suppressed over‐reduction preserves structural integrity and promotes *OCHO pathway, resulting in durable and highly selective electrochemical conversion of CO2 to formate.
