Palladium magnetic nanoparticle-polyethersulfone composite membrane as an efficient and versatile catalytic membrane reactor

摘要

Developing polymer catalytic membrane reactors is an aim due to its outstanding advantages. In this paper, a novel catalytic membrane containing palladium-supported magnetic nanoparticles is introduced. Silica-iron oxide core shell nanoparticles were first prepared and functionalized by phosphine ionic liquid functionalized poly(ethylene glycol). The modified magnetic nanoparticles were used as support for immobilization of palladium. The final palladium-immobilized nanoparticles were used as active filler for the preparation of membrane reactor. The prepared membranes were characterized, and their activities were tested in carbon-carbon bond formation and catalytic reduction. The catalytic membrane showed good performance in the mentioned reactions.
