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

Three kinds of cross linked polystyrene resin (PS) supported ruthenium complexes were developed as catalysts for the synthesis of formic acid from carbon dioxide hydrogenation. Many factors, such as the functionalized supports, solvents and ligands, could influence their activities and reuse performances greatly. These immobilized catalysts also offer the industrial advantages such as easy separation.
