Synergistic Fluorine and Cyanide Co‐Modification to Reinforce Photoinduced Excitons Formation and Transfer for Efficient CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...
