Abstract: Mn(III) tetra (4-methoxyphenyl) porphyrin (MnTMePP) was synthesized inside the nanocages of zeolite-X according to "ship-in-bottle " model. MnTMePP was impregnated (MnP-NaX imp) and encapsulated (MnP-NaX) in the zeolite matrix and had been used as an active heterogeneous catalyst for thymol hydroxylation. The oxidation results were improved by immobilization of metalloporphyrin inside zeolitic faujasite in compression with homogeneous catalyst (MnTMePP). The hydroxylation reaction was performed at 25 ° C and atmosphere pressure by using H 2 O 2 / Ammonium acetate. All catalysts were characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM) Ultraviolet-Visible (UV-Vis) spectroscopy analyses.
