Ni- and Co-incorporated MCM-41 type mesoporous materials with Ni/Si and Co/Si molar ratios of 0.12 were synthesized, characterized, and tested in both steam reforming of ethanol (SRE) and sorption-enhanced steam reforming of ethanol (SESRE) reactions. Characterization results showed that Co and Ni were successfully incorporated and well-dispersed in the mesoporous MCM-41 support. Ni- and Co-incorporated MCM-41 catalysts had surface area values of 449.0 and 303.6 m(2)/g, respectively. They also had narrow pore size distributions, with average pore diameters of 2.2 and 1.98 nm, respectively. SESRE results obtained with these catalysts showed that in situ capture of CO2 during ethanol reforming reaction significantly enhanced hydrogen yield in the temperature range of 500-600 degrees C. The catalytic performance of Ni-incorporated MCM-41 was much better than the Co-incorporated MCM-41, in hydrogen production by ethanol reforming. The highest hydrogen yield value obtained over the Ni-incorporated MCM-41 catalyst was achieved at 600 degrees C as 5.6 in SESRE reaction. This was similar to 94% of the maximum possible hydrogen yield value of 6.0.

Electrochemical polymerization of 9-fluorenecarboxylic acid and its electrochromic device application Bezgin, Buket; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2008-09-01) Poly(9-fluorenecarboxylic acid) (PFCA) was synthesized by electrochemical oxidation of 9-fluorenecarboxylic acid (FCA) using a mixture of nitromethane and boron trifluoride diethyl etherate as the solvent and tetrabutylammonium tetrafluoroborate as the supporting electrolyte. An insoluble and conducting brownish-orange film was deposited on the electrode surface, both during repetitive cycling and constant potential electrolysis at 1.15 V. Characterization of the polymer film has been carried out using Four...
Sorption properties of synthetic ferrierite Karsli, H; Çulfaz, Ali; Yucel, H (2003-05-01) Limiting sorption volumes of the hydrogen form of a synthetic ferrierite sample were determined for sorbates-water, methanol, propane, hexane, and o-, m-, p-xylenes-at 298 K and at a relative pressure of P/P-o= 0.5 using a gravimetric sorption apparatus. Methanol, which has a kinetic diameter significantly smaller than the pore dimensions, was sorbed relatively rapidly and by the greatest amount. The sorption rates of other sorbates were very slow and for some it took several days for equilibrium to be esta...
Polyaniline: synthesis characterization solution properties and composites Yılmaz, Faris; Küçükyavuz, Zuhal; Department of Polymer Science and Technology (2007) Polyaniline was chemically synthesized at three different temperatures of 25, 0, and -25oC, by oxidative polymerization with ammonium peroxidisulfate at equimolar of aniline to oxidant ratio and 1M HCl. The resulted polyaniline was in a powder form which was characterized by several techniques such as: electrical conductivity, elemental analysis, thermal analysis, wide-angle X-Ray diffraction, and scanning electron microscope. The solution properties of the reduced polymer were studied by viscometry, static...
Electrochemical Formation of Alloys of Scandium in Molten Salts polat, çağlar; ERDOĞAN, METEHAN; iplikçioğlu, Safder; Karakaya, İshak (2018-02-01) The Al-Sc alloy formation by the reduction of Sc containing compounds in a molten salt containing CaCl2 was investigated in this study. The preliminary tests revealed that Al3Sc intermetallic, which gives the superior properties to this alloy, was successfully formed and distributed homogeneously throughout the Al matrix. XRD, SEM-EDS and optical microscopy analyses were used to confirm the results.
Electrochemical synthesis of crowned conducting polymers : nature of radical cations in polymerization and mechanism of conductivity Cihaner, Atilla; Önal, Ahmet Muhtar; Department of Chemistry (2004) Poly(dibenzo-18-crown-6) (Poly(DB18C6)) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as solvent and tetrabutylammonium tetrafluoroborate (TBABF4) or tetrabutylammonium hexafluorophosphate (TBAPF6) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in-situ ESR and in-situ UV-VIS spectroscopic techniques. Spectroelectrochemical (SPEL) properties and thermal analysis of the resulting polymers h...
