配位笼基Ⅱ型孔性液体及其催化1-癸烯加氢性能OACHSSCD

To expand the application scope of porous liquids,this study explores their catalytic performance and applications in catalytic reactions by controlling pore size and chemical properties.A coordination cage-based type Ⅱ porous liquid(HD/PEG)was synthesized by dissolving a vanadium oxo-organic molecular cage(HD)into polyethylene glycol(PEG-2000).Palladium acetate(C4H6O4Pd)was then added,and palladium nanoparticles were synthesized in situ within HD/PEG via the reducing capability of PEG-2000.The palladium nanoparticles did not occupy the intrinsic pores of HD.Therefore,the resulting liquid(HD/Pd/PEG)retained a permanent porous structure after the reaction.Under mild conditions(t=40 ℃,p(H2)=1.01×105 Pa),the HD/Pd/PEG catalyst exhibited high catalytic activity for the hydrogenation of 1-decene within 1 h,achieving 99.2％conversion,98.5％selectivity toward the target product decane,and a yield of 97.7％.The synergistic effect between the highly dispersed palladium nanoparticles and the intrinsic porous structure in HD/Pd/PEG significantly enhanced both the conversion in the hydrogenation of 1-decene and the reaction rate.This study demonstrates the promising potential of this type of porous liquid in catalysis and provides important support for further expansion of its application scope.
