Hydrogenation on Palladium Nanoparticles Supported by Graphene Nanoplatelets

Hydrogenation of quinolines, alkenes, and biodiesel by palladium nanoparticles supported on magnesium oxide.

A new catalyst composed of Pd nanoparticles supported on MgO has been prepared by the room temperature NaBH(4) reduction of Na(2)PdCl(4) in methanol in the presence of the support. TEM measurements reveal well-dispersed Pd particles of mean diameter 1.7 nm attached to the MgO surface. Further characterization was achieved by ICP-AES, XPS, XRD, H(2) pulse chemisorption and H(2)-TPR. The new cata...

High catalytic performance of palladium nanoparticles supported on multiwalled carbon nanotubes on alkene hydrogenation

The synthesis of Pd nanoparticles (Pd-NPs) supported on multiwalled carbon nanotubes (MWCNTs) and the cataytic performance of the resulting material (PdNPs/MWCNTs) on hydrogenation reactions are presented. Facile preparation approaches based on the decomposition of Pd precursors in the presence of MWCNTs lead to homogeneous dispersions of supported Pd-NPs with average size of 4 nm and Pd loads ...

Performance comparison of graphene and graphene oxide-supported palladium nanoparticles as a highly efficient catalyst in oxygen reduction

In this work, the performance of graphene nanosheets (GNs) and graphene oxide (GO) nanosheets, as a support for palladium nanoparticles (PdNPs) toward oxygen reduction reaction (ORR), was studied. The graphene nanosheets were functionalized by a new and simple method. The PdNPs were synthesized on a glassy carbon electrode (GCE) modified with GNs or GO via a potentiostatic method; without using...

Palladium Nanoparticles Supported by Alumina Nanofibers Synthesized by Electrospinning

Poly(vinyl)chloride supported palladium nanoparticles: catalyst for rapid hydrogenation reactions.

Palladium nanoparticles supported over poly(vinyl)chloride matrix (PVC-Pd(0)) are prepared through an efficient and inexpensive protocol. The catalyst has been characterized by XRD, SEM and TEM and its utility for the reduction of a range of functional groups as well as for the removal of some common protecting groups employed in peptide chemistry is demonstrated.
