With our study we can concluded that, amphiphilic dendrimer can be well suited for the formation of metal nanopartiles viz., Ag, Pd and PtNPs. Based on the performance of APPI-G2 it was inferred that, other types of dendrimers which having similar properties could also be exploited for the same application. As these nanocatalysts selectively reduce the methyl orange, the same can also be extended to chemo selective reduction of azo dyes having different reducible groups under mild conditions.

In the present study, a stable and convenient form of bead-shaped heterogeneous nanoparticle catalyst viz., PS-PVBC-PPI-(G2)-AuNPs was synthesized using insoluble cross-linked polymer-supported PS-PVBC beads as a matrix and its catalytic activity was examined with Knovenegal condensation reaction. These PS-PVBC-PPI-G2-AuNPs catalyst was able to catalyze the reaction 24 times faster compared to conventional technique. These catalysts maintained its catalytic efficiency even upto five times of recycles.As these catalysts are bead shaped, it can be very well packed into a column reactor and thus...

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...
