Magnetic nanocatalysts with PAMAM dendrimer for Rhodamine degradation
ISBN-13: 9783659797347 / Angielski / Miękka / 2015 / 64 str.
Three types of novel magnetically recoverable core-shell heterogeneous nanoparticle catalysts were prepared by individual grafting of Poly(amidoamine) dendrimer with generation G(0), G(1) and G(2) on Fe3O4-Poly(4-MS-DVB-GMA) core-shell as a common matrix followed by stabilization of AuNPs. The activity of these three catalysts were assessed based on the reduction of Rh-B. The reduction of Rhodamine B reveals that Fe3O4-Poly(4-MS-DVB-GMA)-PAMAM-G(2) is 6 times (kobs = 35.2810-3 min-1) active than the G(0) dendrimer catalyst and its activity is maintained upto 5th cycle thus enlightening the recyclability and stability.These core-shell magnetic nanocomposites possess many future biological applications.
