Highly active and selective photochemical reduction of CO2 to CO using molecular-defined cyclopentadienone iron complexes
2015, Rosas-Hernández, Alonso, Alsabeh, Pamela G., Barsch, Enrico, Junge, Hernrik, Ludwig, Ralf, Beller, Matthias
Herein, we report highly active (cyclopentadienone)iron–tricarbonyl complexes for CO2 photoreduction using visible light with an Ir complex as photosensitizer and TEOA as electron/proton donor. Turnover numbers (TON) of ca. 600 (1 h) with initial turnover frequencies (TOF) up to 22.2 min−1 were observed. Operando FTIR measurements allowed for the proposal of a plausible mechanism for catalyst activation.
