Electrochemical Reduction of CO 2 to CH 3 OH Catalyzed by an Iron Porphyrinoid

Designing catalysts for the selective reduction of CO2, resulting in products having commercial value, is an important area of contemporary research. Several molecular catalysts have been reported to facilitate the reduction of CO2 (both electrochemical and photochemical) to yield 2e–/2H+ electron-reduced products, CO and HCOOH, and selective reduction of CO2 beyond 2e–/2H+ is rare. This is partly because the factors that control the selectivity of CO2 reduction beyond 2e– are not yet understood. An iron chlorin complex with a pendent amine functionality in its second sphere, known to selectively catalyze CO2RR to HCOOH with a very low overpotential from its formal Fe(I) state, can catalyze CO2RR from its…
