摘要:Abstract(#br)Vernonia galamensis is a native weed of Ethiopia containing high concentration of naturally epoxidized oil (glyceryl trivernolate) in its seeds, which could be used as a potential substitute for currently used epoxy oils. Apart from an epoxy group, vernolic acid...

摘要:Abstract(#br)Beta zeolite (nominal Si/Al = 19) has been treated with HF/NH 4 F solutions under different HF concentration, temperature and reaction time. It has been found that the crystallinity of the resulting materials is >80% for HF concentration up to 0.5 M, but it drop...

摘要:Abstract(#br)It is thought that during immobilization enzymes, as dynamic biomolecules, may become distorted and this may alter their catalytic properties. However, the effects of different immobilization strategies on enzyme rigidity or flexibility and their consequences in...

摘要:Abstract(#br)Catalytic performance in the methanol-to-olefins reaction was studied on four 8-ring silicoaluminophosphate (SAPO) molecular sieves with different framework topologies and cavity-windows of various dimensions: SAPO-35 (LEV), SAPO-56 (AFX), STA-7 (SAV), and SAPO-...

摘要:Abstract(#br)Hierarchical Beta nanozeolites with the properties of both Beta nanozeolite and mesoporous material were prepared by two different methods: (1) Direct Hydrothermal Method (DHM) by the assembly of nanocrystals of preformed Beta seeds in the presence of the surfac...

摘要:Abstract(#br)SAPO-35 molecular sieves have been synthesized using different additives. Monosaccharides were employed in order to decrease the crystal size and classical mesoporogen agents (carbon black and chitosan) were combined with the sugar additives to generate small crystal...

摘要:Abstract(#br)A series of selected TiO 2 -Zeolite hybrid photocatalytic materials have been systematically synthesized and analyzed. The synthesized samples were characterized by X-ray diffraction (XRD), elemental analysis (ICP-OES), N 2 adsorption–desorption isotherms, diffu...

摘要:Abstract(#br)The synthesis of small-pore silicoaluminophosphate SAPO-35 ( LEV ) using hexamethyleneimine as organic template and glucosamine as additive is described for the first time. Pure SAPO-35 materials were obtained in short reaction times from gels containing up to 3...

摘要:Abstract(#br)Zeolite Y was treated using ammonium acetate and ammonium fluoride sequentially. As a consequence the aluminum from the surface was selectively removed. Then, loading with TiO 2 (20 wt%) led to a final photocatalyst. The samples were characterized by X-ray diffr...

摘要:Abstract(#br)Beta zeolite was synthesized under hydrothermal conditions using multi-walled carbon nanotubes with an outer diameter of 8–15 nm as a nanometric template. The textural, structural, and acidic properties were characterized by X-ray diffraction, thermogravimetric ...
