Microwave-assisted synthesis of Pd nanoparticles supported on Fe3O4, Co3O4, and Ni(OH)2 nanoplates and catalysis application for CO oxidation

Environmental implications and applications of engineered nanoscale magnetite and its hybrid nanocomposites: A review of recent literature

“…Pt decorated octahedral Fe3O4 catalyst prepared by addition of a Pt 4+ and Fe 2+ mixture into a KOH solution leads to the simultaneous formation of an octahedral Fe3O4 and in situ reduction of Pt 4+ , which exhibits excellent catalytic activity for CO oxidation under moisture conditions [212]. In another study, Pd NP catalysts supported on Fe3O4, Co3O4, and Ni(OH)2 nanoplates are used in the low temperature oxidation of CO and the Pd/Co3O4 catalyst has particularly high activity for CO oxidation as a result of the strong interaction between the Pd NPs and the Co3O4 nanoplates [213]. PtNPs (1.2±0.1 nm) synthesized in situ on MNPs (32 nm) previously deposited on alumina supports, is highly active towards the preferential oxidation of CO in a H2-rich reformate stream and gives 100 % CO conversion at 25 °C.…”

Polyvinylpyrrolidone - Reduced Graphene Oxide - Pd Nanoparticles as an Efficient Nanocomposite for Catalysis Applications in Cross-Coupling Reactions

“…It is widely known that one of the most important processes in the field of organic synthesis is the carbon-carbon bond formation through crosscoupling reactions that are catalyzed by transition metals. Those types of reactions are widely used in many areas like agricultural, medicinal, and pharmaceutical applications [11][12][13]23,[38][39][40][41][42]. The new synthetic trends are mainly focused recently on using catalysis at the nano scale for green chemistry using microwave assisted synthesis [11][12][13]15,16,18,20,22,23,[40][41][42][43][44][45][46].…”

“…Furthermore, the outstanding characteristics of Gaphene enabled its combination with other metallic and bi-metallic nanoparticle catalysts which can be used in various chemical reactions and transformations. Moreover, the defects in the graphene lattice structure enabled an easy and excellent process of anchoring the metals like palladium at the nanoscale to the surface of Gaphene leading to tunable metal-support interaction through surface functionalities [11][12][13][14][15][16][50][51][52]. The role of polyvinylpyrrolidone (PVP) as a non-toxic, water soluble, and low-cost linear polymer is that it can simply enable forming film stability besides enhancing the chemical properties.…”

“…The defect sites in the reduced Graphene oxide (rGO) act as nucleation centers that enable anchoring of both Pd/PVP nanoparticles and hence, minimize the possibility of agglomeration which leads to a severe decrease in the catalytic activity.one of the main interests that attracted researchers' attention is transition metals based materials, especially when using palladium nanoparticles [5][6][7][8][9][10]. It is well established that palladium-based catalysts have been widely used in homogeneous and heterogeneous catalysis due to their several outstanding properties that combine between those of single metal atoms and other bulk metals [11][12][13][14][15][16]. In order to design new compounds with tailored chemical and…”
