• 1,3-Dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole (BIH) was used as reductant.
• The photocatalytic activity Ru–Re for CO2 reduction was drastically improved.
• ΦCO = 0.45, TONCO = 3029, TOFCO = 35.7 min−1.
• These are the best photocatalysis results using supramolecular complexes.
We found a very suitable sacrificial electron donor, 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole (BIH), to demonstrate the proper ability of a Ru(II)–Re(I) supramolecular photocatalyst for CO2 reduction. The efficiency, durability, and rate of the photocatalytic reaction were drastically improved (ΦCO = 0.45, TONCO = 3029, TOFCO = 35.7 min−1) using BIH as an electron donor compared to that using 1-benzyl-1,4-dihydronicotinamide as an electron donor (ΦCO = 0.15, TONCO = 207, TOFCO = 4.7 min−1). The reasons for the improvement were clarified based on the detailed mechanistic investigations.
