Characterization of AlFe-pillared Unye bentonite: A study of the surface acidity and catalytic property
Çağlar, Bülent; Çubuk, Osman; Demir, Ersin; Çoldur, Fatih; Çatır, Mustafa; Topcu, Cihan; Tabak, Ahmet (Elsevier Science Bv, 2015)Aluminium-iron-pillared bentonite has been prepared by incorporation of the iron mixed aluminium-polyoxocation into bentonite layers and characterized by the powder X-ray diffraction, Fourier transform infrared, thermal ... -
Experimental and theoretical study on the structure and vibrational spectra of β-2-aminopyridinium dihydrogenphosphate
Çırak, Çağrı; Demir, Selçuk; Ucun, Fatih; Çubuk, Osman (Elsevier, 2011)Experimental and theoretical vibrational spectra of ?-2- aminopyridinium dihydrogenphosphate (?-2APDP) have been investigated. The FT-IR spectrum of ?-2APDP was recorded in the region 4000-400 cm -1. The optimized molecular ... -
The spectral, structral and thermal characterizations of dimethyl sulphoxide, pyridine, ethanolamine and N-methyl formamide intercalated kaolinites
Çağlar, Bülent; Afşin, Beytullah; Eren, Erdal; Tabak, Ahmet; Çırak, Çağrı; Çubuk, Osman (Verlag der Zeitschrift fur Naturforschung, 2010)The intercalation of dimethyl sulphoxide (DMSO), pyridine (Py), ethanolamine (Ea), and Nmethyl formamide (NMF) molecules into the kaolinite interlayers led to an appreciable decrease of 3697 cm-1 of the hydroxyl band. The ... -
Structural characterization of hexadecyltrimethylammonium-smectite composites and their potentiometric electrode applications
Çubuk, Osman; Çağlar, Bülent; Topçu, Cihan; Çoldur, Fatih; Sarp, Gökhan; Tabak, Ahmet; Şahin, Erdal (Elsevier, 2015)Organosmectites were prepared by the intercalation of hexadecyltrimethylammonium cations at various ratios into interlayer of Unye smectite. Structural, thermal, morphological and textural properties of the synthesized ...
