Pd Nanoparticles Supported On Copper Oxide Prepared Via Microwave – Assisted Synthesis: An Efficient Catalyst For Suzuki Cross-Coupling, Hany A. Elazab Dr

Chemical Engineering

We report here a scientific investigation of a simple and versatile synthetic rote for the synthesis of palladium nanoparticles decorated with copper oxideand supported on reduced Graphene oxide (rGO) as a highly active catalyst usedfor Suzuki, Heck, and Sonogashira cross coupling reactions with remarkable turnover number (7000) and turnover frequency of 85000 h^-1. Pd-CuO nanoparticles supported on reduced Graphene oxide nanosheets (Pd-CuO/rGO) exhibited an outstanding performance through high catalytic activity towards cross coupling reactions. A simple, reproducible, and reliable method was used to prepare this efficient catalyst using microwave irradiation synthetic conditions. The synthesis approach requires simultaneous reduction …

Hydrothermal Synthesis Of Graphene Supported Pd/Fe3o4 Nanoparticles As Efficient Magnetic Catalysts For Suzuki Cross – Coupling, Hany A. Elazab Dr

Chemical Engineering

This research reports a reproducible, reliable, and efficient method for preparing palladium nanoparticles dispersed on a composite of Fe3O4 and graphene as an active catalyst with high efficiency for being used in Suzuki cross – coupling reactions. Graphene supported Pd/Fe3O4 nanoparticles (Pd/Fe3O4/G) exhibit a remarkable catalytic performance towards Suzuki coupling reactions. Moreover, the prepared catalyst recyclability was up to nine times without losing its high catalytic activity. The catalyst was prepared using hydrothermal synthesis; the prepared catalyst is magnetic in order to facilitate catalyst separation out of the reaction medium after reaction completion simply through using a strong magnet.
