摘要：
The amine functionalized silica immobilized ruthenium complexes used for CO2 hydrogenation to formic acid were prepared in an in situ synthesis way. The formic acid turnover frequency of 1384 h(-1) at 100% selectivity has been obtained in CO2-expanded ethanol over Si-(CH2)(3)-NH(CH2)(3)CH3-Ru, while NEt3 used as base, which was significantly higher than homogeneous ones.
