In this paper, Fe, Ce and Ti metals were subjected to the zeolite structure using postsynthesis treatment and identified by FT-IR, XRD, FESEM, EDX, BET spectroscopy techniques. Figure 1a showed the presence of peaks in related to CeO 2 and Fe 2O3 which demonstrated the insertion of metals in zeolite structure. Fig. 1b, c shows FESEM and EDS analysis of catalyst which proved the preservation of zeolite structure with cubooctahedral units based on metal doping. The improved photocatalytic activity was investigated in the photodegradation of 4-Nitrophenol [1,2]. Photocatalytic activity of this system depends on the catalyst loading, H 2O2 content, pH, 4-Nitrophenol concentration and temperature effect [3]. The COD results reveal that 4-NP was degraded to simple materials. Pseudo-first order kinetic was suggested for photodegradation reaction.
