Pd nanoparticles entrapped in chitosan superfine fibers as a highly active and stable catalyst for the Mizoroki–Heck reaction

抄録

Pd/chitosan/polyacrylate sodium composite fibers (Pd@CS/PAA) with average diameter of (152 ± 30) nm were prepared by electrospinning. The composite fibers were subsequently cross-linked at 160 °C to improve their solvent stability. TEM results showed that entrapment of palladium species into the composite fibers could increase its dispersion. The composite fibers were found to be very active and stable to catalyze the Mizoroki–Heck reaction of iodobenzene with n-butyl acrylate. Therefore, a highly active and stable heterogeneous palladium catalyst can be prepared by entrapping the palladium nanoparticles in CS/PAA composite fibers.
