Germanium is known to occupy tetrahedral sites by substituting silicon in germanosilicate zeolites. In this study, we present pioneering findings regarding the synthesis of zeolites with an MFI structure (GeMFI) incorporating a high germanium amount (16% Ge). Remarkably, atoms feature slight electron deficiency respect GeO2, and typical coordination number 4, as usually reported for zeolites, exceeded, giving rise Ge dimers double-bridge configuration. Notably, compensation ammonium template...
A tough challenge in nanomaterials chemistry is the determination of structure multicomponent nanosystems. Dye–zeolite L composites are building blocks hierarchically organized multifunctional materials for technological applications. Supramolecular organization inside zeolite nanochannels, which governs electronic properties, barely understood. This especially true confined close-packed dye molecules, a regime not investigated applications yet and that might have great potential future...
The host–guest and guest–guest interactions governing the CO2 adsorption/desorption in two nanosized zeolite samples with FAU framework type different Si/Al ratios (Na–X = 1.24 Na–Y 2.54) cation distribution were investigated by situ synchrotron high-resolution X-ray powder diffraction (XRPD) Fourier transform infrared (FTIR) spectroscopy. complementary techniques allow probing zeolites at levels, that is, average structure XRPD versus local FTIR spectroscopy . presence of physisorbed...
Highly efficient, separable, and stable magnetic iron-based-photocatalysts produced from ultra-stable Y (USY) zeolite were applied, for the first time, to photo-Fenton removal of phenol under solar light. USY Zeolite with a Si/Al molar ratio 385 was impregnated vacuum an aqueous solution Fe2+ ions thermally treated (500-750 °C) in reducing atmosphere. Three catalysts, Fe-USY500°C-2h, Fe-USY600°C-2h Fe-USY750°C-2h, containing different amounts reduced iron species entrapped zeolitic matrix,...
Abstract Turning disorder into organization is a key issue in science. By making use of X‐ray powder diffraction and modeling studies, we show herein that high pressures combination with the shape space constraints hydrophobic all‐silica zeolite ferrierite separate an ethanol–water liquid mixture ethanol dimer wires water tetramer squares. The confined supramolecular blocks alternate binary two‐dimensional (2D) architecture remains stable upon complete pressure release. These results support...
The quantitative phase analysis using the Rietveld method is one of most used analytical protocols for characterization several types natural and synthetic materials, it can be performed both on fully crystalline multiphase systems materials containing even an amorphous fraction. Therefore, there are applications this (e.g., to raw traditional ceramics, bricks, glass-ceramics, cementitious binders, etc.). More recently, application has disseminated also in chemical, pharmaceutical, other...
The HP behavior of the natural zeolite yugawaralite and synthetic Na-A was studied by in situ synchrotron X-ray powder diffraction, using a non-penetrating P-transmitting medium. unit-cell parameters were refined up to pressure 10 GPa, at which reductions found about 7, 2.4, 1.3, 15% for a, b, c, β, V, respectively. Contractions 6.5 18.4% respectively, range 10-4 6.8 GPa. Diffraction patterns collected during decompression show that effects induced high on both samples are almost completely...
In this work, metal-ceramic nanocomposites were obtained through short (up to 2 h) thermal treatments at relatively moderate temperatures (750–800 °C) under a reducing atmosphere, using Fe-exchanged zeolite A as the precursor. The as-obtained materials characterized by X-ray powder diffraction analysis, N2 adsorption –196 °C, and highresolution transmission electron microscopy. results of these analyses showed that consisted dispersion metallic Fe nanoparticles within porous ceramic matrix,...
