英文摘要	The catalyst (Co4H1PV2 Mo10O40/PaAPTES) of heteropoly acid cobalt salt supported on acid activated and silanizing palygorskite (PaAPTES) by 3-aminopropyl-triethoxysilane (APTES) was prepared via chemical bonding. The properties of the catalyst was characterized by infrared spectroscopy, X-ray diffraction, Brunauer-Emmett-Teller (BET) specific area measurement. The catalytic activity of the catalyst was determined by the oxidation of toluene to benzaldehyde. The results show that benzaldehyde is the main product in the reaction. With the acetonitrile as solvent, the amount of catalyst is 0.3 g, the amount of H2O2 (50% in volume) solution is 9.6 mL, after reaction at 90°C for 9 h, the conversion of toluene is 58% and the selectivity of benzaldehyde is 75%. The recycling tests show that the catalyst can be easily separated from the reaction system.
