Abstract
 The use of dimethyldichlorosilane as a coupling agent for the grafting of VOx structures on the MCM-48 surface produces a material that is simultaneously hydrophobic (immiscible with water) and very active (all V-centers are accessible, even for water molecules). These hydrophobic MCM-48 materials supported VOx catalysts are stable up to 500 degrees C and show a reduction in the leaching of the V-centers in aqueous media by a factor of 4. Also, the structural stability has improved significantly. The crystallinity of the silylated materials does not decrease significantly after a hydrothermal treatment in an autoclave at 160 degrees C. (C) 2000 Elsevier Science B.V. All rights reserved.
