Shape-controlled nanoscale FeOx and Au/Fe3O4 catalysts with an inverse spinel structure were prepared and tested for the oxidative dehydrogenation of cyclohexane. The reaction was studied in situ in SAXS/TPRx mode with isothermal steady-state holds.

Layered MCM-22(P) was synthesized in the presence of hexamethonium (HM) cations. Compared to zeolite EU-1 (EUO-type structure), which crystallizes in similar conditions, its formation is favored at high HM concentrations (HM/SiO2 ≥ 0.3) and in the

Shape controlled zeolite EU-1 (EUO) catalysts were synthesized by a dry gel conversion (DGC) type synthesis. Silica extrudates as starting material were impregnated to the incipient wetness point and subjected to a hydrothermal treatment under water

Am Beispiel der Umsetzung von Allylalkohol zu Glycidol wird gezeigt, dass eine Epoxidierung mit Sauerstoff als Reaktionspartner in einem Prozessschritt moglich ist. Die Bildung von Wasserstoffperoxid durch kathodische Reduktion von Sauerstoff in eine
Advanced zeolite EU-1 catalysts were prepared by impregnation of macroporous alpha alumina beads with zeolite precursors followed by dry gel conversion (DGC). The composition of impregnated precursors was significantly affected by leaching from alumi

Zeolite EU-1 has been synthesized by dry gel conversion starting from low alkali containing precursors. A detailed study comparing this synthesis method to alkali-rich precursor systems and a classical hydrothermal synthesis has been achieved. A low
