Despite the fact that metastable aluminum oxides are actively used in industry, there is a discrepancy literature regarding their crystal structure. All this leads to difficulties data interpretation and, as consequence, classification problems. This work aimed at solving these tasks. The main features of powder X-ray diffraction typical samples three Al2O3 polymorphs (γ-, χ-, η-) analyzed. Specifics and fundamental differences scattering relationship with structural organization...
High dispersion and low degree of crystallinity supported MoS2 nanoparticles have almost excluded the conventional X-ray diffraction (XRD) analysis from a range physical methods for characterization molybdenum-based hydrotreating catalysts. High-resolution transmission electron microscopy (HRTEM) remains powerful preferred technique obtaining information on stacking slabs. Here, we report new approach to study in catalysts basis XRD data. Alumina-supported were investigated by means Debye...
Abstract For the first time, detailed structure of χ-Al 2 O 3 and η-Al surface has been established by implementing NMR crystallography approach. The demonstrated to be formed primarily (111) facets, while is a combination (110) facets. This observation supports block model aluminum oxides previously proposed Tsybulya Kryukova [S. V. Tsybulya, G. N. Kryukova, Phys. Rev. B 77 (2008) 024112.]. additional terminal OH groups, observed experimentally not contributing theoretical calculations, are...
Abstract DIANNA is a free software developed to simulate atomic models of structures for an ensemble nanoparticles and calculate their whole X-ray powder diffraction patterns the radial distribution function. The main objects investigation are particles whose coherent scattering domains do not exceed several nm. based on ab initio method using Debye equation. This makes it possible obtain information structure, shape size nanoparticles. It can be applied also non-periodic materials or...
Solid soda lime sorbents are promising materials for CO2 removal in closed-circuit breathing systems. In this study, the sorbent Drägersorb 800+ has been tested a fixed bed reactor. The changes composition, structure, and texture of occurring process sorption have studied using thermogravimetry, X-ray diffraction analysis, nitrogen adsorption (BET), mercury porosimetry scanning electron microscopy methods. A non-stationary model developed simulating chemisorption bed. results simulation...
Abstract The metastable nanocrystalline γ-Ga 2 O 3 with the particles’ dimensions about nm was prepared by coprecipitation method and its structure studied using X-ray powder diffraction. corresponding diffraction pattern is characterized a strong broadening of peaks. Debye function analysis (DFA) applied to calculate full profile XRD for first time. Earlier reported structural models were examined respect experimental data. influence crystallite sizes on considered. obtained disordered has...
