Highly efficient, selective, and durable photocatalytic system for CO2 reduction to formic acid. Issue 12 (29th September 2015) - Tamaki, Yusuke
Abstract : Photocatalytic reduction of CO2 to formic acid with high efficiency, durability, and rate. Abstract : We discovered an extremely suitable sacrificial electron donor, 1, 3-dimethyl-2-( o -hydroxyphenyl)-2, 3-dihydro-1 H -benzo[ d ]imidazole, for the selective photocatalytic reduction of CO2 to formic acid using a Ru(ii )–Ru(ii ) supramolecular photocatalyst. The efficiency, durability, and rate of photocatalysis are significantly increased ( Φ HCOOH = 0.46, TONHCOOH = 2766, TOFHCOOH = 44.9 min −1 ) in comparison with those using 1, 3-dimethyl-2-phenyl-2, 3-dihydro-1 H -benzo[ d ]imidazole or 1-benzyl-1, 4-dihydronicotinamide.
