摘要：

There is widespread interest in the hydrogenation of CO2 to produce high-energy substances such as formic acid. Herein, ruthenium trichloride was immobilized on porous phosphine polymers (Ru/KAPs-Ph-PPh3) and gave excellent catalytic activity in the hydrogenation of CO2 to produce formate. With the assistance of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), a high turnover number (TON) of up to 1470000 was obtained in 12 hours at 120 & DEG;C and a total pressure of 6 MPa (P(H-2)/P(CO2)=1 : 1), with average TOFs of 122500 h(-1). Moreover, the catalyst can be easily recovered by filtration with acceptable catalytic effectiveness.
