a powerful and convenient reaction procedure for the c-n coupling reaction (the buchwald-hartwig reaction), yielding products of n-arylanilines and n-arylamines in both conventional heating and microwave irradiation has been reported. the protocol utilizes a stable and new supper ferromagnetic nanoparticle chelating n-heterocyclic dicarbene palladium(ii) complex (pd-nhc) as catalyst which helps...

We report on one-step hybridization of silver, gold and palladium nanoparticles from solution onto exfoliated two-dimensional (2D) Ti3C2 titanium carbide (MXene) nanosheets. The produced hybrid materials can be used as substrates for surface-enhanced Raman spectroscopy (SERS). An approximate analytical approach is also developed for the calculation of the surface plasmon resonance (SPR) frequen...

OF THE DISSERTATION Biomimetic Catalysts of Graphene Conjugates and Palladium Nanoparticles

Palladium nanoparticles were deposited with high dispersion and stability on nitrogen-doped magnetic carbon nanoparticles by a simple impregnation method, and their catalytic performance was investigated for Heck, Suzuki, and Sonogashira coupling reactions.

The development of green and safe processes for the synthesis of nanomaterials is one of the main aspects of nanotechnology. In this study, a biological, inexpensive and rapid process for the fabrication of palladium nanoparticles using the aqueous broth of Pistacia Atlantica fruit as a novel biomass product is reported without using extra surfactant, capping agent, and template. The synthesize...

Due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple and low cost method is very important. In this work, Pd nanoparticles were synthesized with narrow size distribution by loading metal salt (Pd(OAc)2 ) into the polymeric matrix (PEG) as reducing agent and stabilizer. Also, the effect of metal salt concentration and PEG molecular weight on the con...

RNA sequences have been discovered that mediate the growth of hexagonal palladium nanoparticles. In vitro selection techniques were used to evolve an initial library of approximately 10(14) unique RNA sequences through eight cycles of selection to yield several active sequence families. Of the five families, all representative members could form crystalline hexagonal palladium platelets. The pa...

Sustainable methods are needed to recycle precious metals and synthesize catalytic nanoparticles. Palladium nanoparticles can be produced via microbial reduction of soluble Pd(II) to Pd(0), but in previous tests using dissimilatory metal reducing bacteria (DMRB), the nanoparticles were closely associated with the cells, occupying potential reductive sites and eliminating the potential for cell ...

Palladium nanoparticles were deposited and reduced by gelatin as a safe edible, naturally occurring and cheap support. No extra reducing agents were used for the generation of Pd(0) nanoparticles from the Pd(II) salt. The nanoparticles of Pd supported on gelatin were characterized by SEM, TEM and AFM images, UV-Vis and XRD spectra and the amount of palladium entrapped in the gelatin was measure...

Nanoparticles of palladium-doped cerium oxide (Pd–CeO2) have been prepared by aqueous co-precipitation resulting in a single phase cubic structure after calcination according to X-ray diffraction (XRD). Inhomogeneous strain, calculated using the Williamson–Hall method, was found to increase with palladium content, and the lattice contracts slightly, relative to nano-cerium oxide, as palladium c...
