Electron-Withdrawing Ligand Modulation of Pt Sites in a Covalent Organic Framework for Photocatalytic CO2-to-CH4 Conversion.
Photocatalytic CO2-to-CH4 conversion in water remains challenging because selective multielectron proton-coupled reduction requires efficient charge separation and controlled intermediate hydrogenation. Herein, we report an electron-withdrawing-ligand-regulated Pt-site covalent organic framework, Pt-LEW/TBCOF, for sele...
