Abstract

MnTiO3-Zeolite-Y nanocomposites were synthesized with 5-10-20% (w/w) of MnTiO3 by stearic acid gel method. Then, the gels were calcined at 900 °C for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. Also, the presence of rhombohedral phase of MnTiO3 in Zeolite-Y matrix was confirmed by XRD, SEM, EDX and BET. The VSM results showed the antiferromagnetic properties for the 20% nanocomposite. The photocatalytic activity of the nanocomposites was finally evaluated by degradation of methylene blue and calcon reagents in aqueous solution.
