摘　　要：A series of Mo-impregnated H\%β\% samples, with MoO\-3 loading in H\%β\% zeolite in the mass fraction range of 0\^5%\_6\^0%, were studied by means of XRD and IR in order to characterize their structures. Mo/H\%β\% samples′ crystallinity almost linearly decreases with increasing the amount of MoO\-3 loaded. The IR spectra and XRD patterns suggest that the progressive destabilization of the H\%β\% zeolite structure is caused by increasing Mo loading in (MoO\-3+H\%β\% zeolite). During the calcination, Al\-2(MoO\-4)\-3 formed from the dealumination of H\%β\% zeolite, causes the substantially partial breakdown of the zeolite framework when the Mo loading in MoO\-3+H\%β\% is relatively high.A series of Mo-impregnated H\%β\% samples, with MoO\-3 loading in H\%β\% zeolite in the mass fraction range of 0\^5%\_6\^0%, were studied by means of XRD and IR in order to characterize their structures.
