In this paper we report synthesis of Fe2TiO5–5A zeolite (Z5A) nanocomposites with 5%, 10% and 20% weight percent of Fe2TiO5 in 5A zeolite in stearic acid media after calcination of the gel samples obtained at 600–900°C for 2 hrs. The powder X–RAY diffraction (XRD) patterns have been used for characterization of the prepared samples. The Scanning Electron Microscopy (SEM) images and X–ray Energy Dispersion (EDX) results were used to determine the size and composition of Fe2TiO5–Z5A nanocomposites. Differential porosity value of Fe2TiO5–Z5A nanocomposite samples in comparison with the 5A zeolite were obtained by Brunauer–Emmett– Teller (BET) method. A Vibrating Sample Magnetometer (VSM) was used to determine magnetic behavior of 20% Fe2TiO5–Z5A and pure Fe2TiO5. The results indicated the change of erromagnetism to the superparamagnetism behavior due to the small particle size and a high value of calcan and methylene blue degradation (63 and 99% respectively) for 20% Fe2TiO5–Z5A.
