Abstract

Visible-light driven CO₂ reduction is considered to be a sustainable energy source. However, earth-abundant molecular catalysts with high efficiency and robustness towards solar-driven CO₂ reduction are limited. Herein, we report a cobalt complex supported by a tetradentate tripodal ligand, which demonstrates catalytic solar-driven CO₂ reduction with TON(CO) > 900 over 70 h in the presence of a photosensitizer.
