Regulating Defect‐Coordinated Single‐Iron‐Atom Catalysts for Efficient Nitrate Reduction Reactions

Carbon Energy, EarlyView.
This figure illustrates the ball‐and‐stick model of an asymmetric monatomic Fe─N2 catalyst and its catalytic process for converting nitrate to ammonia. Shown are the adsorption configurations of precursors and intermediates (NO3− → NO2− → NO → NH2OH → NH3) on the catalyst surface, where brown represents iron atoms, red represents oxygen atoms, dark ...

Asymmetric‐Coordinated Indium Single Atoms for Highly Selective Photocatalytic CO2 Reduction

Carbon Energy, EarlyView.
This work develops an indium single‐atom photocatalyst (In‐NTO) featuring unique Inδ⁺–N3O2 coordination sites for highly selective CO2 photoreduction. The specific atomic interface steers the reaction pathway exclusively toward CO (95.9% selectivity) by lowering the overall energy barrier and converting the critical *CO protonation step from ...

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

Multiple Active Sites Engineering in Cu/γ‐Al2O3 Catalyst Enables Selective Electrocatalytic CO2 Reduction to Methane at High Rates

Carbon Energy, EarlyView.
A multi‐site heterogeneous electrocatalyst is designed, composed of Cu nanoclusters supported on γ‐Al2O3. Within this system, CO2 activation, H2O dissociation, and *CO protonation are respectively governed by the Cu sites, γ‐Al2O3 sites, and the Cu/γ‐Al2O3 interface sites.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
