Visible-light-driven reduction of CO2 to CO in fully aqueous media using a water-soluble cobalt porphyrin†
Abstract
Herein we report a water-soluble cobalt porphyrin that efficiently catalyzes the photoreduction of CO2 in fully aqueous media. Under visible light irradiation CO is produced as a main product (TONCO = 2500, TOFCO = 1200 h−1) with a good selectivity over H2 production (SelCO2 = 74%).
