Nanocrystals of MgO (4 nm) exist as polyhedral structures with high surface concentrations edge/corner sites. In powder form the crystallites weakly agglomerate into porous weblike approximately 1400 nm according to small-angle X-ray scattering. Upon consolidation these fine powders under pressure, pellets can be readily prepared that maintain their areas, and small crystallite sizes. addition, large pore volumes size openings controllably decreased pelletization pressure increase. The...
Aerogel preparation of MgO and CaO nanoparticles involves a sol−gel approach where methoxides are converted to hydroxide gels followed by hypercritical drying vacuum dehydration. This produces, for these particular hydroxides/oxides, ultrafine particulates rather than monoliths. These particulate materials have exhibited unexpectedly high surface chemical reactivities that allowed their successful use as high-capacity destructive adsorbents toxic chemicals, including chlorocarbons,...
Formation of radical anions after adsorption 1,3,5-trinitrobenzene (TNB) on electron donor sites fully oxidized Al2O3 samples with different phase compositions is studied by EPR. It shown that the maximum concentration does not substantially depend choice solvent and reaction temperature, can be used to measure total sites. The are observed in almost same about 5 × 1016 m−2 all alumina polymorphs except for α-Al2O3. formation rate TNB activation energy this process found properties solvent....
A series of supported Pd/ZrO₂ catalysts with Pd loading from 0.2 to 2 wt % was synthesized. The ZrO₂ material prepared by a similar technique used as reference sample. samples have been characterized means transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), testing reaction ethane hydrogenolysis (HGE), N₂ adsorption, and paramagnetic resonance (EPR) spectroscopy. 1,3,5-trinitrobenzene probe...
We studied the formation process of a mayenite structure from hydroxide precursors in different gas media. According to X-ray diffraction data, this method allows well-crystallized (Ca12Al14O33 or C12A7) phase be obtained at low (500-900 °C) temperatures with an insignificant impurity CaO. It was shown that lattice parameters for C12A7 inert atmosphere (Ar) were lower when compared similar samples air. These results can explained by levels oxygen nonstoichiometry resulting phase. noted...
Small amounts of vanadium or carbon added to nanocrystalline MgO aerogels were shown promote their activity in destructive sorption CF2Cl2 and CFCl3 halocarbons. This reaction is characterized by a prolonged induction period, which considerably shortened after the addition studied promoters. It was demonstrated that promoting effect finely dispersed did not depend on its location relative nanoparticles. Approximately same results obtained when deposited as thin layer surface nanoparticles,...
The carbon coating hinders the sintering of δ-Al<sub>2</sub>O<sub>3</sub> phase. stabilization nanosized oxide particles in Al<sub>2</sub>O<sub>3</sub>@C system is considered as decisive factor preventing their transformation to α-Al<sub>2</sub>O<sub>3</sub>
In situ ESR spectroscopy has been used for direct comparison of different thermal and light-induced processes leading to generation superoxide radical anions on the surface various zirconia sulfated materials. For materials both types magnetic resonance parameters were found be practically independent method, except oxygen coadsorption with NO that yields radicals somewhat smaller gz values. The appear depend mostly state cations stabilizing anions, so g tensor anisotropy is significantly...
