We present here a novel fabrication of highly effective supported Pd catalysts (Pd@S-1@IL) derived from Pd@S-1 core-shell material coated with ionic liquids (ILs), [Prmim][Cl], for the selective hydrogenation of acetylene. Catalytic testing on Pd@S-1@IL catalyst illustrated a remarkable selectivity towards semi-hydrogenation (over 90% for ethylene, irresp. of conversion level). Moreover, no indications of deactivation were observed after 800 h on stream even under relatively severe conditions. Detailed characterization indicated that the selectivity enhancement was ascribed to the filter effect along with electronic effect on the adsorption/desorption processes arising from the ionic liquids layer. The stability, which has ranked the top reported values over advanced Pd-based catalysts, is attributed to the confinement effect of Pd NPs within the supports thus restricting the migration of metals. The fabrication of core-shell architecture combined with the advantages of ionic liquid layer offers a promising guideline for efficient catalytic transfer of chem. resource. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Related Products of 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Related Products of 79917-89-8
