Abstract

We discovered an extremely suitable sacrificial electron donor, 1,3-dimethyl-2-(-hydroxyphenyl)-2,3-dihydro-1-benzo[]imidazole, for the selective photocatalytic reduction of CO to formic acid using a Ru(ii)-Ru(ii) supramolecular photocatalyst. The efficiency, durability, and rate of photocatalysis are significantly increased ( = 0.46, TON = 2766, TOF = 44.9 min) in comparison with those using 1,3-dimethyl-2-phenyl-2,3-dihydro-1-benzo[]imidazole or 1-benzyl-1,4-dihydronicotinamide.

摘要

我们发现了一种极其合适的牺牲电子供体，即1,3-二甲基-2-（-羟基苯基）-2,3-二氢-1-苯并咪唑，用于使用Ru（ii）-Ru（ii）超分子光催化剂将CO选择性光催化还原为甲酸。与使用1,3-二甲基-2-苯基-2,3-二氢-1-苯并咪唑或1-苄基-1,4-二氢烟酰胺相比，光催化的效率、耐久性和速率显著提高（=0.46，TON=2766，TOF=44.9分钟）。
