Hoch aktiv auf engem Raum: Das Polyoxometallat H3PW12O40, das in den Kanälen von mesoporösem Siliciumoxid hydrophoben Alkylgruppen umgeben ist (siehe Bild), zeigt eine außergewöhnlich hohe katalytische Aktivität bei der Esterhydrolyse Wasser. Wegen basierenden Nanostruktur kann die wässrige Reaktionsmischung aktiven Zentren einfach erreichen, obwohl sie Einheiten sind.

Abstract A typical coated diamond has been examined by x-ray diffraction and absorption topography. At the commencement of coat an abrupt change to fibrous, radial growth occurs. This mode gives rise general spherical habit thickly diamonds. In specimen studied range misorientation in fibrous was 0·43° about fibre axis 0·25° a normal axis. Fibre diameters ranged up some tens microns. X-ray contrast produced more opaque layers indicated maximum local impurity concentrations 0·7% MgO or SiO2,...
Sn-Beta modified with cations such as Li and Na showed better catalytic performance than non-modified “open” sites in Baeyer–Villiger oxidation.
Functional inner space: A gigantic ring-shaped {Mo154} polyoxometalate cluster anion can be stabilized by encapsulation in dimethyldioctadecylammonium (DODA) cations. Its nanospace enables adsorption of gases and vapors, it acts as a water-tolerant solid acid catalyst (see scheme). Detailed facts importance to specialist readers are published "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted the authors.

We investigated photocatalytic reduction of NO3– in real groundwater the presence photocatalyst Pt/TiO2 and nonphotocatalyst SnPd/Al2O3, which were dispersed groundwater, under irradiation at λ > 300 nm, with glucose as a hole scavenger. In this system, H2 evolution (2H+ + 2e– → H2) proceeded over Pt/TiO2, nonphotocatalytic, that is, conventional catalytic, (NO3– 5/2H2 1/2N2 2H2O OH–) occurred SnPd/Al2O3. (1.0 mmol dm–3) completely selectively decomposed to N2 (yield 83%) after 120 h W Xe...
The palladium oxidation state of an SiO2-supported catalyst was quantitatively determined by Pd L3-edge XANES (X-ray absorption near-edge structure) analysis. By changing the time CO-reduction pre-treatment at 673 K, a series 5 wt% Pd-loaded SiO2 catalysts (PdOx/2/SiO2) containing different amounts metal and PdO phases were prepared, average number (x) estimated from CO2 molecules formed during treatment. spectra these samples reference sample (Pd powder) recorded, white line area evaluated....
Alongside TiO2, Magneli-phase titanium suboxide having the composition of TinO2n–1 is a kind attractive functional materials composed titanium. However, there still remain problems to be overcome in synthesis suboxide; existing methods require high temperature typically over 1000 °C and/or postsynthesis purification. This study presents novel approach nanoparticles through solid-phase reaction TiO2 with TiH2. Crystal phases were easily controlled by changing TiO2/TiH2 molar ratios TiO2–TiH2...
