Abstract V-P/Si02 samples obtained by impregnation and grafting with different contents of vanadium and phosphorus have been studied by ESR, scanning electron microscopy (SEM) and fine-structure x-ray absorption (FSXA). It is shown that, independent of the method of synthesis, the vanadium concentration and the P/V ratio, the surface region of the carrier consists of a crystalline β- VOPO4 phase with a low concentration of V4+ ions.
