Catalysts containing tungsten or molybdenum in the form of Keggin type heteropolyacids, like H3PW12O40, H4SiW12O40 and H3PMo12O40, supported on silica gel were prepared. The acid and surface properties of heteropolyacids and their supported forms are discussed. Keggin type heteropolyacids supported on silica gel have been found active for propene metathesis, the activity was compared with those of the classical catalyst WO3/SiO2. The highest activity and selectivity for studied reaction showed catalyst prepared on the base of H3PW12O40.
