Herein the modifications of a glassy carbon electrode (GCE) with palladium nanoparticles and a palladium film are reported. The response to hydrogen peroxide on the modified electrode was examined using cyclic voltammetry and amperometry (at –0.2 V vs. Ag/AgCl reference electrode in the phosphate buffer solution, pH 7.4). The palladium film and palladium nanoparticle-modified GCE showed a linea...

We report a facile route to selectively deposit and arrange palladium (Pd) nanoparticles on single-walled carbon nanotubes (SWCNTs) having sub 10 nm diameter by using supramolecular self-assembly of sodium dodecyl sulfate (SDS) as a soft template.

Palladium nanoparticles, simply and briefly generated in commercial and cheap onium salts using supercritical carbon dioxide, have been found to be an effective catalytic system for additive free N-alkylation reaction using alcohols via cascade oxidation/condensation/reduction steps.

the objective of this study was to assess the potential of cadmium sulfide nanoparticles loaded onto activated carbon (cdsn-ac) for the removal of sunset yellow (sy) dye from aqueous solution. adsorption studies were conducted in a batch mode varying solution ph, contact time, initial dye concentration, cdsn-ac dose. in order to investigate the efficiency of sy adsorption on cdsn-ac, pseudo-fir...

This paper presents a new gel combustion method to synthesize palladium nanoparticles, palladium oxide (PdO) nanoparticles and palladium-palladium oxide nanocomposites. In the proposed method, there are some effective parameters including palladium chloride concentration, polyvinyl alcohol (PVA) concentration, acid concentration, solvent composition and combustion temperature that their values ...

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

Glassy carbon foam (GCF) catalyst supports were synthesized from waste polyurethane elastomers by impregnating them in sucrose solution followed pyrolysis and activation (AC) using N2 CO2 gas. The palladium nanoparticles formed Pd(NO3)2. are highly dispersive because the mean diameters 8.0 ± 4.3 (Pd/GCF), 7.6 4.2 (Pd/GCF-AC1) 4.4 1.6 nm (Pd/GCF-AC2). Oxidative post-treatment of resulted formati...

Catalytic activities of palladium catalysts supported on activated carbon and carbon nanotubes were investigated in the one-pot synthesis of R-1phenylethyl acetate in combination with an immobilized lipase in toluene. Palladium catalysts on carbon nanotubes with nitrogen-containing surface groups were prepared by incipient wetness impregnation. The basic N-CNT support was synthesized by post-tr...

Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The eff...
