Abstract

Abstract : A new iron–nitrogen doped carbon and CdS hybrid system was developed to efficiently reduce CO2 to CO under UV/vis light (AM 1.5G) irradiation in aqueous solution. Abstract : Iron porphyrin and carbon black (CB) were utilized to fabricate an iron–nitrogen doped carbon (Fe–N–C) catalyst to create a new heterogeneous catalytic system with CdS to drive CO2 reduction to CO under UV/vis light (AM 1.5G) irradiation. The system delivers a high CO production yield of 111 mmol gcat −1 and a large turnover number (TON) of 1.22 × 10 3 in 8 h with a selectivity of 85%, all of which are competitive with state-of-the-art systems. The mechanism of the system was investigated by experimental and theoretical methods indicating that the high affinity between the iron active center and the *COOH intermediate facilitates the brilliant catalytic performance. This work provides a new direction for constructing heterogeneous CO2 photoreduction systems.
