Abstract:


A new Pt metal based nanocatalytic system was developed using organic inorganic magnetic framework followed by user friendly protocol in good yield. XRD, FTIR, TEM, BET, ICP-OES and solid-state NMR techniques were used to characterize our developed catalytic system. The well characterized ionic liquid bridged-silica supported magnetic Pt nanoparticles were utilized for the selective hydrogenation of carbon dioxide under high pressure reaction condition (with and without ionic liquid medium). Most promising results were obtained while using the catalytic system (Pt-MagNP@IL-SiO2) in 1,3-di (N, N-dimethylaminoethyl)-2-methylimidazolium nonafluorobutanesulfonate ([DAMI][CF3CF2CF2CF2SO3]) task specific ionic liquid medium. This TSIL not only provided high degree of CO2 absorption during the reaction but also enhances the selectivity and the recyclability of the catalytic system up to 8 runs. No sign of Pt metal leaching was recorded during the recyclability test which confirmed stability of this catalytic system under high pressure reaction condition.
