Facile approach to the electrochemical synthesis of palladium-reduced graphene oxide and its application for Suzuki coupling reaction

Graphene supported heterogeneous catalysts: An overview

“…The TEM analysis of the Pd/graphene catalyst system indicates that agglomeration of the Pd nanoparticle on the surface of graphene occurs once the cycling process reached 10 times [215]. This phenomenon is related to the deactivation of Pd/graphene catalyst which involves the reduction of surface area and saturation of the coordination site [217]. The electron rich labile support system appears to stabilize the catalyst center, brought to deactivation by agglomeration, which finally enhances the cross-coupling catalytic performance [216].…”

This was due to the fact that doped nitrogen atoms can increase the electrical conductivity through partial structure recovery and provide efficient anchor sites for well dispersed metallic nanoparticles on the surface of carbon support [247,268,269].…”

Surfactant‐Exfoliated Highly Dispersive Pd‐Supported Graphene Oxide Nanocomposite as a Catalyst for Aerobic Aqueous Oxidations of Alcohols

“…[21][22][23][24][25] Nagarkar and co-workers reported the catalytic activity of Pd-nanoparticle-supported GO (Pd@GO) in SuzukiMiyaura cross-coupling reactions. [24] Various reduced binary noble metals (Pt, Ag, Pd)s upported on GO are also recyclable catalysts developed for similar chemistries including Pd-catalyzed Suzuki reactions. [24,26] Recently,b oth Pd@RGO and Pd@GO were employed as catalysts in the oxidation of alcohols.…”

Exfoliated Pd decorated graphene oxide nanosheets (PdNP–GO/P123): Non-toxic, ligandless and recyclable in greener Hiyama cross-coupling reaction

“…Recently palladium supported graphene oxide (Pd/GO) is found to be efficient, recyclable, and convenient catalyst which is generated by reduction of Pd ions on the surface of GO [14][15][16][17]. This is due to suitable interaction of Pd species with carbon based structures.…”
