In this work and for the first time, bimetallic Ag-Pd nanoparticles equipped with a core-shell structure were prepared biologically by employing a galvanic displacement reaction in which the added PdCl2 reacts with an Ag nanotemplate containing an adsorbed soaproot (Acanthe phylum bracteatum) extract. Four samples with different Ag/Pd molar ratios of 100:2, 100:5, 100:10 and 100:15 were prepared to synthesize the bimetallic nanoparticles with a core-shell structure. The bimetallic Ag-Pd nanoparticles were characterized using UV-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), scanning electron microscopy with an energy-dispersive X-ray spectroscopy (SEM-EDX), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) analysis. The results from UV-Vis revealed an optimal molar ratio of 100:15 for Ag/Pd, which is appropriate to prepare bimetallic Ag-Pd nanoparticles with the core-shell structure. The results of FTIR and XRD confirmed the pure bimetallic Ag-Pd nanoparticles formation. The images prepared by TEM depicted spherical and uniformly shaped nanoparticles without any agglomeration and a particle size of 15 nm.

Development of Ru0/MO2 (M = Ti, Zr, Hf, Ce) catalysts for electrocatalytic hydrogen production from water splitting Demir, Elif; Önal, Ahmet Muhtar; Department of Chemistry (2017) In this study, Ru0/MO2 catalysts were prepared by reduction of ruthenium(III) chloride on different types of metal oxides, which were TiO2, ZrO2, CeO2 and HfO2, then catalysts were loaded on glassy carbon (GC) electrodes at same mass loading level, and used as electrocatalysts in 0.5 M H2SO4 solution for hydrogen evolution reaction (HER). Characterization of prepared catalysts were done by using transmission electron microscopy (TEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) spectroscopy and X...
Preparation of Chitosan-Coated Magnetite Nanoparticles and Application for Immobilization of Laccase Kalkan, Nuzhet Ayca; AKSOY, SERPİL; Aksoy, Eda Ayse; Hasırcı, Nesrin (2012-01-15) In this study, immobilization of laccase (L) enzyme on magnetite (Fe(3)O(4)) nanoparticles was achieved, so that the immobilized enzyme could be used repeatedly. For this purpose, Fe(3)O(4) nanoparticles were coated and functionalized with chitosan (CS) and laccase from Trametes versicolor was immobilized onto chitosan-coated magnetic nanoparticles (Fe(3)O(4)-CS) by adsorption or covalent binding after activating the hydroxyl groups of chitosan with carbodiimide (EDAC) or cyanuric chloride (CC). For chitosa...
High performance Pt nanoparticles prepared by new surfactants for C-1 to C-3 alcohol oxidation reactions ŞEN, FATİH; Gökağaç Arslan, Gülsün; Sen, Selda (Springer Science and Business Media LLC, 2013-09-07) In this study, platinum nanoparticles have been prepared using PtCl4 as a starting material and 1-hexylamine, N-methylhexylamine, N,N-dimethylhexylamine, 1-heptylamine, N-methylheptylamine, and N, N-dimethylheptylamine as surfactants. All these surfactants were used in this synthesis, for the first time, to explore the effect of primary, secondary, and tertiary amine and chain length on the size and catalytic activity toward C1-C3 alcohol electro-oxidation. The electrochemical performance of all catalysts w...
A new soluble conducting polymer and its electrochromic devices YİLDİZ, UMİT HAKAN; SAHİN, ELİF; Akhmedov, IM; Tanyeli, Cihangir; Toppare, Levent Kamil (Wiley, 2006-04-01) A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(1-phenylethyl)-2,5-di(2-thienyl)-1H-pyrrole (PETPy). Of which the chemical method produces a polymer that is completely soluble in organic solvents. The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1 and C-13 NMR) and Fourier transform infrared (FTIR) spectroscopy. The average molecular weight has been determined by gel permeation chrom...
PREPARATION AND CHARACTERIZATION OF POLYMER COATED SMALL UNILAMELLAR VESICLES OZDEN, MY; Hasırcı, Vasıf Nejat (1991-09-02) Glucose oxidase was entrapped in small unilamellar vesicles composed of phosphatidylcholine, dicetyl phosphate and cholesterol. Prediction of the enzyme content of liposomes by calculations based on input concentrations of lipid and protein, dimensions of the lipids and the liposomes yielded one protein per vesicle. The entrapment efficiency was experimentally determined to be about 13%. On the other hand the entrapment efficiency for the small chromate ions was found to be significantly lower (0.1%). T...
