چکیده مقاله :
In recent years, the concentration of carbon dioxide (CO2) in the air has reached its highest level due to human activities. Therefor, the improvement sustainable strategies to capture CO2 and then its conversion into valuable compounds has received greater attention.[1] For example, cyclic carbonates widely used in the industry can be produced via the coupling of CO2 with epoxides. In recent years, mesoporous organosilica materials have attracted much attention as a kind of porous organic-inorganic hybrids due to their specific features.[2] Herein, nickel(II) supported on the mesoporous organosilica nanoparticle with the dipicolinic thioester frameworks (Ni@SNS-MON) has been described as an efficient recoverable catalyst for title reaction. It was found that CO2 could couple with various types of epoxides to the corresponding cyclic carbonates in the presence of 0.1 mol% Ni@SNS-MON and 0.3 mol% tetrabutylammonium bromide (TBAB) as co-catalyst at 100 °C
