Ultrathin 2D In₂O₃ Nanosheets Confining Cu Single Atoms Synergized With Oxygen Vacancies for High Selectivity of Photocatalytic Reduction of CO₂ to CO. [PDF]

Adv Sci (Weinh)
In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure based on oxygen vacancies (OV)‐rich defects and low crystallinity to anchor Cu single atoms (Cu SAs) and synthesized Cu/In2O3‐Ns photocatalysts. ABSTRACT In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure ...

Unlocking Zenith Electronic State of Ni Sites in Ligand-Engineered COFs for Efficient •O₂ ^--Driven Uranium Photoreduction. [PDF]

Adv Sci (Weinh)
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.

Designing covalent organic frameworks with Co-O4 atomic sites for efficient CO2 photoreduction

Nature Communications, 2023
A class of inexpensive aminoanthraquinone organic dyes are shown to facilitate visible-light-driven CO_2 reduction. Overall reaction efficiencies were found to be optimal when both electron donating and accepting groups were on a single dye molecule ...
