Polyoxometalate (POM) catalysts with different trivalent hetero ions (Mⁿ⁺ = Fe³⁺, Al³⁺, and Cr³⁺) were prepared by incipient wetness impregnation method and supported on different zeolites namely, NaY, ZSM-5 and Mordenite. The intended catalysts samples were distinguished by X-ray diffraction, FTIR and surface texture measurements. The data given disintegration in the crystallinity of zeolite structure, enlarge in particle size and new phases of metal oxides Al₂(MoO₄)₃ and Fe₂(MoO₄)₃ were exposed by XRD and FTIR techniques. These phases caused widening of pores of the employed zeolites and change of the surface texture. The physical changes indicate the considerable interaction of polyoxomolybdate with the zeolite structure. The assessment of the catalytic activity was thorough by applied the photocatalytic degradation of direct blue 1 dye (DB1) in existence of H₂O₂ as a green oxidant. The catalytic activity of Mⁿ⁺Mo-ZSM-5 sample is higher than that of Mⁿ⁺Mo-Y or Mⁿ⁺Mo-Mord.
