摘　　要：Three heteropoly acids containing different amounts of V and Mo have been prepared by multi-step method. The methed was simple, economic in raw materials’ cost, and with relatively higher yield. ICP, TGA, Potentiometric Titrations, Infrared, XRD and 51V NMR characterizations revealed that the compounds synthesized in present work had Keggin structure. The catalytic performance of the heteropoly acids obtained for the direct hydroxylation of benzene to phenol was also investigated, 26% phenol yield with more than 90% selectivity was obtained.
