Selective Synthesis of N,N‐Dimethylformamide From CO2 Hydrogenation Coupled With Dimethylamine Over a ZnZrOx Solid‐Solution Catalyst

Carbon and Hydrogen, EarlyView.
N‐formylation of dimethylamine though CO2 hydrogenation takes place at a ZnZrOx solid‐solution catalyst surface toward N,N‐dimethylformamide. By synergistic effect of Zn and Zr sites, the catalyst achieves 99% DMF selectivity at 14% DMA conversion at 280°C with at least 1000 h stability on steam.

An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

Carbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

Simultaneous Photoactivation of Copper and Ti‐Doped CeO2−x Enables Optimal Acceleration of the RWGS Reaction

Carbon Energy, EarlyView.
A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

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 ...
