Effective catalytic removal of 4-nitrophenol (4-NP) in industrial wastewater remains a significant challenge due to the lack highly efficient and stable catalysts. Herein, we demonstrated promising plasma method for facile, ultra-fast low-temperature synthesis graphite oxide (GO)-supported palladium catalyst (Pd/GO-P) rich oxygen-containing groups (OCGs) defects with smaller Pd nanoparticles (N...

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...

Low molecular weight chitosan (LMWC) is a promising polymer for surface modification of nanoparticles (NPs), which can impart both stealth effect and electrostatic interaction with cells at mildly acidic pH of tumors. We previously produced LMWC-coated NPs via covalent conjugation to poly(lactic-co-glycolic) acid (PLGA-LMWC NPs). However, this method had several weaknesses including inefficienc...

The synthesis of palladium, platinum and ruthenium nanoparticles stabilized by azamacrocycles bearing polyoxyethylenated chains has been achieved by decomposition of the corresponding organometallic precursors (Pd(dba)(2), Pt(2)(dba)(3) and Ru(COD)(COT)) under dihydrogen atmosphere, whereas gold and rhodium nanoparticles have been obtained in the presence of these ligands by reduction of HAuCl(...

The purpose of this study was to design and synthesize Palladium nanoparticles (PdNPs) using an environmentally friendly approach and evaluate the in vitro efficacy of PdNPs in human ovarian cancer A2780 cells. Ultraviolet-Visible (UV-Vis) spectroscopy was used to monitor the conversion of Pd(II) ions to Pd(0)NPs. X-ray diffraction (XRD) revealed the crystallinity of the as-synthesized PdNPs an...

Stoichiometric reactions of Pd(0) nanoparticles with various amounts of white phosphorus (P4) are an efficient route to convert them into the corresponding Pd phosphides Pd(x)P(y). Formation of crystallized palladium phosphide nanoparticles is a two-step process, which allows exploring in detail the phase transitions of the Pd(x)P(y) system, from amorphous Pd-P nanoparticles (formed in a first ...

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 ...

Palladium porous single-crystalline nanoflowers (PSNFs) with enriched high catalytic activity {100} facets were synthesized using a mild and controllable seed mediated growth method. The growth mechanism of the Pd PSNFs was investigated using time dependent morphology evolution through TEM imaging. Due to the specific structure, Pd PSNFs show highly enhanced ethanol oxidation reaction (EOR) act...

−We have successfully synthesized morpholinium ionic liquid-stabilized palladium (Pd) nanoparticles by electrochemical reduction. For characterization of Pd nanoparticles, FT-IR, UV-visible spectroscopy, and Transmission electron microscopy (TEM) were employed. The FT-IR spectrum of Pd nanoparticles indicated the surface binding of the IL to the nanoparticles. The UV-visible spectrum showed tha...

Palladium nanoparticles supported on carbon black powder (Vulcan XC-72) nanocomposite (Pd/C) are synthesized as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterization of the catalyst is carried out using physical and electrochemical methods. It is observed that Palladium nanoparticles are uniformly dispersed onto the carbon blac...
