photocatalytic and magnetic behavior of fe2tio5-5a zeolite nanocomposites

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 ferromagnetism 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.
