Abstract
This work is presented to evaluate the influence of titanium dopant on the various properties of barium ferrite nanoparticles (BaFe2O4). Ba1_xTixFe2O4+(delta )with x varying from 0.0 to 1.0 were prepared by chemical technique. The titanium doping results in creation of cationic vacancies with the increased surface area. The crystalline size was decreased with the enhanced Ti4+ doping process. The saturation magnetization was decreased with the increased Ti4+ content. Photocatalytic properties of un-doped and doped BaFe2O4 was investigated for alizarin yellow (AY) dye. The Ba0.3Ti0.7Fe2O4.7 nanoparticles act as the best photocatalyst with the degradation potential (100.0 %). The enhanced photocatalytic amount was obtained due to the narrowing of band gap of Ba0.3Ti0.7-Fe2O4.7 (2.07 eV). The stability and reusability test shows that the amount of degradation was negligibly decreased after 5th cycles. Thus, the Ti4+ doped barium ferrite proved to be great method in modifying the photocatalytic response in the degradation process. Antibacterial analysis depicts that the high content of Ti4+ doped barium ferrite showed higher antibacterial properties against Staphylococcus aureus and Helicobacter pylori.
