Zeolite framework stabilized gold(0) nanoclusters were prepared by the ion-exchange/impregnation of Au3+ ions with zeolite-Y followed by reduction of the Au3+ ions using sodium borohydride in aqueous solution, all at 50 degrees C. The zeolite framework stabilized gold(0) nanoclusters were isolated as red powder and characterized by HR-TEM, TEM, TEM-EDX, XRD, XPS, DR-UV-vis, SEM, ICP-OES spectroscopic methods and N-2-adsorption technique. This new material was found to be highly active, selective and reusable catalyst in the aerobic oxidation of benzyl alcohol under mild conditions.

Development of novel Ag/bauxite nanocomposite as a heterogeneous catalyst for biodiesel production Bet-Moushoul, Elsie; Farhadi, Khalil; Mansourpanah, Yaghoub; Molaie, Rahim; Forough, Mehrdad; Nikbakht, Ali Mohammad (2016-07-01) Ag/bauxite nanocomposites have been prepared using in situ reduction of aqueous AgNO3 solution in a bauxite matrix and investigated for the transesterification of sunflower oil with methanol in order to study their potential as heterogeneous catalysts. The prepared nanocopmosites were characterized by XRD, SEM, EDX, FT-IR, and TG- DTA. The Central Composite Design of the Response Surface Methodology was used to optimize the effect of reaction temperature, reaction time, catalyst loading and methanol to oil ...
The Chemistry of Ethyl 3-(2-Ethoxy-2-oxoethyl)-1H-indole-2-carboxylate: Synthesis of Pyrimido[4,5-b]indoles and Diethyl 4-Hydroxyquinoline-2,3-dicarboxylate via Intramolecular Cyclizations KAPTI, Tolga; Dengiz, Çağatay; BALCI, METİN (2017-04-01) We report the synthesis of a new series of 2-oxo-1,2,4,9-tetrahydro- 3H-pyrimido[4,5-b] indole derivatives and diethyl 4-hydroxyquinoline- 2,3-dicarboxylate starting from ethyl 3-(2-ethoxy-2-oxoethyl)- 1H-indole-2-carboxylate. Intramolecular cyclization formed the target ring systems. The key substrates featuring both acyl azide and isocyanate functionalities were prepared from bis(acyl azide) intermediate. The acyl azide functionalities directly connected to methylene groups were regiospecifically converte...
The preparation and characterization of nano-sized Pt-Pd/C catalysts and comparison of their superior catalytic activities for methanol and ethanol oxidation Ozturk, Zafer; Sen, Fatih; Sen, Selda; Gökağaç Arslan, Gülsün (2012-12-01) In this study, two groups of carbon supported PtPd samples with different percentages of metals were prepared to examine the effects of Pd and stabilizing agents on the catalytic activity towards methanol and ethanol oxidation reactions. As a stabilizing agent, 1-hexanethiol and 1,1-dimethyl hexanethiol were used for group "a" and "b" catalysts, respectively. Cyclic voltammetry, chronoamperometry, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy, and X-ra...
The characterization of polyaniline and polypyrrole composites by pyrolysis mass spectrometry Hacaloğlu, Jale; Kücukyavuz, Zühal (2009-09-05) hi this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and structural characteristics of electrochemically prepared polyaniline (PANI), polypyrrole (PPy), and their composites/copolymers synthesized either by electrochemical polymerization of pyrrole on PANI-coated electrode (PANI/PPy) or by coating PANI on PPy (PPy/PANI) in H(2)SO(4) solutions. It has been determined that the polymer first coated on the electrode degraded to a certain extent during...
Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination Oren, EE; Tas, AC (1998-05-06) Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
