In this study, the preparation of CeTPP(OH)n/TiO2/NaY catalysts were performed using zeolite synthesis and impregnation methods respectively. XRD studies showed that based on incorporation of the metal complex into zeolite nanocage, crystallinity of the zeolite matrix is unchanged. In addition, the presence of peaks in the 2=28 indication of TiO2 in anatase form which proved insertion of TiO2 in nanopores of zeolite. The catalyst displays an efficient photoactivity for the degradation of 4-NP in absence of H2O2.
