Abstract

Herein we report an earth-abundant photocatalytic system for CO₂ reduction to CO based on an iron catalyst combined with a Cu^I photosensitizer. Under visible light irradiation CO is produced as the main product (TON_CO = 565, TOF^max_CO = 114 h⁻¹) with a high selectivity over H₂ production (Sel_CO₂ = 84%).
