A significant decrease in the amount of the sacrificial electron donor triethanolamine (TEOA) required for the homogeneous photocatalytic reduction of CO2 using rhenium-based catalytic systems can be achieved by adding small quantities of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to the reaction mixture. The turnover numbers (TONs) and frequencies (TOFs) measured for the reactions described herein are even higher than those observed in reaction mixtures containing high concentrations of TEOA. Furthermore, replacing TEOA with DBU in the solutions of Re(i)/Ru(ii) mixed catalytic systems leads to a doubling of the values of TON and TOF.
通过向反应混合物中添加少量的1,8 - 二氮杂双环[5.4.0]十一碳 - 7 - 烯（DBU），可以显著减少使用铼基催化体系进行CO₂均相光催化还原所需的牺牲电子供体三乙醇胺（TEOA）的量。本文所述反应测得的周转数（TONs）和频率（TOFs）甚至高于在含有高浓度TEOA的反应混合物中观察到的值。此外，在Re(i)/Ru(ii)混合催化体系的溶液中用DBU替代TEOA会使TON和TOF值翻倍。
