CHARACTERIZATION OF HIGH-SILICA MORDENITE OBTAINED BY DIRECT SYNTHESIS
Three high-silica mordenite zeolites differing in SiO440, ratio were prepared by direct synthesis without using any template. The products Si02/A120, ratio is influenced by the starting gel composition. This ratio is increased upon ion-exchange with NH,Cl and subsequent calcination to prepare protonic mordenite. The protonic mordenites with Si02/A1203ra tios of 14.6,29.2 and 34.6 were chara...

متن کاملA new high-pressure silica phase obtained by molecular dynamics—Discussion
pressure silica phase (which they denoted SBAD) with space group Pnc2 from molecular dynamics (MD) simulations. However, we noticed that a simple cell transformation for the reported structural data of the SBAD phase results in a structure that is virtually the same as the well known α-PbO2 type SiO2 structure with space group Pbcn, as previously described by Matsui and Kawamura (1987) and Mats...
متن کاملSilica-based mesoporous organic-inorganic hybrid materials.
Mesoporous organic-inorganic hybrid materials, a new class of materials characterized by large specific surface areas and pore sizes between 2 and 15 nm, have been obtained through the coupling of inorganic and organic components by template synthesis. The incorporation of functionalities can be achieved in three ways: by subsequent attachment of organic components onto a pure silica matrix (gr...
متن کاملSynthesis of Fe-doped CeO2 Nanoparticles Prepared by Solgel Method
Nanomaterials have achieved remarkable technological advances in bulk materials due to their excellent physical, chemical and biological properties. cerium oxide (CeO2) nanostructured doped with Fe ions is attractive due to improvement in redox properties, transport property and surface-to-volume ratio. In this research, Fe-doped CeO2 nanoparticles (NPs) were prepared by s...
