Abstract Commercial bentonite from the Kopernica deposit, Slovakia, is currently mined by CERTECH Company, Poland, to produce materials intended for animal-care applications and other industrial purposes. The present study aimed assess mineralogical, petrographic physicochemical characteristics of three varieties used company. X-ray diffraction, optical microscopy, field emission scanning electron microscopy (FESEM), nuclear magnetic resonance, thermal analysis, infrared spectroscopy...
Montmorillonite is a layered clay mineral whose modification by pillaring, i.e., insertion of oxide nanoclusters between the layers, yields porous materials great potential in sorption and catalysis. In present study, an unrefined industrial bentonite from Kopernica (Slovakia), containing ca. 70% montmorillonite, was used for preparation Ti-, Zr-, mixed [Ti,Zr]-pillared sorbents. The pillared samples were characterized with X-ray diffraction (XRD), field emission scanning electron microscopy...
Abstract A series of V-doped titania-pillared clay catalysts, characterized by ICP-AES chemical analysis, X-ray diffraction, BET surface area measurement, and ESR spectroscopy, have been tested in the selective catalytic reduction NO NH 3 . An analysis shows that V dopant is anchored to titania pillars. Vanadyl species with differing degrees in-plane V-O π-covalent bonding are produced depending on method sample preparation. Polymeric appear as content increased. Catalytic performance these...
Cu-doped Al-, Ti-, and Zr-pillared montmorillonites obtained by various procedures have been investigated with the aid of electron spin resonance (ESR). The major species present in pillared exchanged copper at low pH are physisorbed square planar tetraaquo-complexes [Cu(H 2 O) 4 ] 2+ . Only surface uncalcined Al pillars does a chemisorption ions occur, giving an inner-sphere complex [Cu(AlO) n (H 4- x Calcination samples 673 K brings about significant change Cu ion environment reflected ESR...
