Boosting C=O Bond Scissoring Over a Pyridinic Nitrogen‐Modified Cu–MoC Interface for High‐Efficiency CO2 Hydrogenation to CO

open access: yesCarbon Energy, EarlyView.
ABSTRACT Reverse water‐gas shift (RWGS) reaction‐aided sustainable CO2 conversion has emerged as one promising and effective approach for simultaneously mitigating climate change and solidifying energy security. Molybdenum carbide‐based catalysts demonstrate excellent selectivity for sustainably transforming CO2 into CO product, but harsh carburization

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

open access: yesCarbon 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

On the Usability of Pt/Al2O3 Catalysts for Exhaust Gas After Treatment in Ammonia Combustion Engines

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonia engines emit no CO2 but exhibit elevated emissions of NH3 and NOx, where conventional SCR systems are not effective due to the significant excess of NH3. This study investigates Pt‐based oxidation catalysts in a bypass configuration to adjust the NH3/NOx ratio, analyzing catalyst parameters and their impact on N2O formation to identify optimal ...
