For large systems containing hundreds of atoms in the unit cell, as usually is observed in the zeolitic materials, the use of periodic ab initio calculations is limited by the requirement of huge computation re
Hydrothermal Synthesis and Structural Characterization of Zeolite-like Structures Based on Gallium and Aluminum Germanatesion exchange, zeolites, molecular sieves, crown ethers, claysgermanium, Gegallium, Gaaluminum, Alstructure (solids and liquids

(2014), ChemInform Abstract: Preparation, Structural Characterization, and Ion-Exchange Properties of Two New Zeolite-like 3D Frameworks Constructed by ε-Keggin-Type Polyoxometalates with Binding Metal Ions, H11.4 [ZnMo12O40Zn2]1.5- and H7.5 [Mn0.2Mo12O40Mn2] 2.1-. ChemInform, 45: no. doi...
Modulating the structures of subnanometric metal clusters at the atomic level is a great synthetic and characterization challenge in catalysis. Here, we show how the catalytic properties of subnanometric platinum clusters (0.5–0.6 nm) confined in the sinusoidal 10R channels of purely siliceous MF...
Then, vacant T sites in the Si-Beta zeolite reacted with the organometallic Ti complex Cp2TiCl2 and Ti species were incorporated into the framework of Beta zeolite upon the calcination. The effect of the acid activation on the titanosilicate having –Ti-O-Ti-chains is the most interesting. ...
Although the current body of literature mostly centers on synthesis and characterization of supramolecular biopoly- mers and their utilization in medicine, there is a noticeable paucity of research examining their potential applications in the agricultural sector. Hence, due to the lack of exten- sive...
Characterization The IR spectroscopy, potentiometric titration, and chemical analysis of surface compounds were performed to confirm the presence of functional groups in the silica matrix. FT-IR spectra of the mesostructures were obtained in transmission mode using Thermo Nicollet NEXUS FT-IR spectrophotome...
XRD, N2-adsorption isotherms, acidity measurements and XPS spectroscopy as well as the catalytic activity in CO2 reforming of methane were used to characterize the solids. The performance measured with the bimetallic nickel and platinum catalysts dispersed on beta zeolite indicate a major improvement ...
