摘　　要：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 80℃ with total pressure of 16.0 MPa. The catalyst can be separated from the reaction mixture easily and reused with moderate loss of activity.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 80℃ with total pressure of 16.0 MPa.
