英文摘要	The surface of acid-activated attapulgite (ATP) was modified by grafting 3-aminopropyltriethoxysilane (APTES) for the immobilization of heteropolyacid salt Co4HP2Mo15V3O62 (CoHPAs). The samples were characterized by Fourier transform infrared spectroscopy, X-ray powder diffraction, specific surface area measurements, thermal analysis and field emission scanning electron microscopy. The catalytic activity was tested for the oxidation of ethylbenzene in the presence of 50 % H2O2 for the first time in this work. It was found that the activity of the ATP supported CoHPAs catalyst is obviously influenced by APTES grafting. The CoHPAs/ATPAPTES catalyst exhibits high activity owing to the silylation of ATP, with the conversion of ethylbenzene and selectivity of acetophenone up to 72.7 and 95.4 %, respectively. The results also show that the CoHPAs/ATPAPTES catalyst can be reused at least five times without significant decrease of activity. © 2013 Akade´miai Kiado´, Budapest, Hungary.
