Rich‐Electronic Interface Promoting Hydrogen‐Bond Reversible Formation for Ultra‐Stable and Energy‐Efficient Catalytic CO2 Capture

Carbon Energy, EarlyView.
Bridging micro–macro scales, a biomass‐derived Ni@C interface creates electron‐rich sites and hydrogen‐bond proton‐relay pathways, tuning interfacial charge and reversible hydrogen bond to enhance carbon capture capacity. Verified by in situ spectroscopy, multi‐scale simulations, and long‐term industrial testing, this system enables low‐temperature and

Unlocking Thermodynamic‐Kinetic Synergy via Rh/Co Dual Sites and Ordered Interfacial Hydrogen‐Bond Network for Efficient Biomass Electrooxidation

Carbon Energy, EarlyView.
An amorphous RhOx‐decorated cobalt‐deficient Co3O4 catalyst is designed for efficient HMF electro‐oxidation to FDCA. This design enables Rh/Co dual sites for enhanced HMF/OH− adsorption thermodynamics while independently ordering interfacial water into a connected hydrogen‐bond network that accelerates proton transfer kinetics, delivering outstanding ...

B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Countercation Manipulation Enables Selective Electrochemical CO2‐to‐Formate Conversion Over Bi‐Polyoxometalate‐Derived Catalysts

Chemistry – A European Journal, EarlyView.
Ba2+ salt of Bi‐incorporated polyoxometalate (POM), Bi4 ([Bi4O(γ‐SiW10O36)2(OAc)]7−), immobilized on a carbon support (Ba‐Bi4/C) functioned as a formate (HCOO−)‐selective catalyst for electrochemical CO2 reduction reaction (CO2RR). The incorporation of Ba2+ and the formation of highly dispersed Bi species were the key factors for Ba‐Bi4/C to achieve ...
