Abstract

Summary

A photochemical reduction of CO2 to CO was shown using the cobalt complex [Fe(qpy)(H2O)2][ClO4]2 or the iron complex [Co(qpy)(H2O)2][ClO4]2 as catalysts in combination with the ruthenium-based photosensitizer Ru(bpy)3Cl2 or the organic dye sensitizer purpurin. Turnover numbers (TONs) up to xx and selectivity of xx for CO were reached in xx. The experiments were conducted under visible-light irradiation (λ = 460 nm) using BIH as sacrificial reductants (see section SEDs below).
