Fund Project: This work was financially supported by the National Natural Science Foundation of China (No. 20173048), the Specialized Research Fund for the Doctoral Program of Higher Education (No. 20030335068), the Scientific Research Fund of Zhejiang Provincial Education Department (No. 20040320) and Zhejiang Provincial Natural Seience Foundation of China (No. Y405088).

A novel efficient catalyst for the hydrogenation of carbon dioxide to formic acid ruthenium bisphosphine on functionalized silica was in situ synthesized, affording turnover frequency (TOF) of 1190 h^-1 at 100% selectivity under 80C with total pressure of 16.0 MPa. The catalyst can be separated from the reaction mixture easily and reused with moderate loss of activity.
