Microporous metallosilicates for the oxidation of hydrocarbons: preparation, characterization and catalytic activity~+

摘要

Metallosilicates containing Cr, Cu or Mo have been prepared by an acid-catalyzed solgelprocess. Structural information about the silicates was obtained by elemental analysis,TGA, XRD, XRF, N2-physisorption, EPR, UV/VIS and FTIR spectroscopy. The silicates areactive catalysts for the oxidation of hydrocarbons with tert-butyl hydroperoxide. Catalyststabilities with regard to metal leaching during catalytic oxidations were investigated.
