Abstract:

Magnetic TS-1 was synthesized with nanosized nickelferrite particles as nuclei via the hydrothermal synthesis and solvent vaporation method. The prepared samples were characterized with N2 adsorption-desorption isotherms, FTIR spectrometry, Raman spectrometry, X-ray diffraction, Ultraviolet-visible spectroscopy and Vibrating sample magnetometry. The results show that the composite obtained was composed of TS-1 with MFI structure and NiFe2O4 with spinel structure, its specific surface area was about 316 m2/g, pore volume was 0.12 cm3/g and pore size distribution was in the range of 0.5-0.7 nm. The catalytic activity of the composite was also investigated by its catalyzing the decomposition of rhodamine B oxidized by H2O2 in aqueous solution. In this case Rhodamine B pollutant could be completely degraded within 150 min. Magnetic TS-1 exhibited high photocatalytic efficiency and super paramagnetic nature for cleaning polluted water with the help of magnetic separation.
