Abstract

The metal-free visible-light-driven CO₂ reduction reaction was achieved by using a fluorine-atom-modified COF, i.e. N3F4-COF, which exhibited over a 5-fold enhancement compared to the pristine COF for syngas production. The activity can be further improved by incorporating a Ru-based photosensitizer, and the syngas ratio could be regulated from 2.57 to 0.14 (CO/H₂) by altering the hydrophilicity of the photosensitizers.
