Synthesis of spinel Tin ferrite decorated on Bismuth ferrite nanostructures for synergetic photocatalytic, superior drug delivery, and antibacterial efficiencies

Abstract The present study shows that the sono-chemically synthesis of SnFe2O4/BiFeO3 nanocomposites for the photocatalytic performance. The crystal structure of SnFe2O4/BiFeO3 nanocomposites evaluated using XRD analysis. The micrograph images displays the support of SnFe2O4 on BiFeO3. The optical status were examined using UV-Vis spectroscopy and the narrower band gap (1.67 eV) was determined for SnFe2O4/BiFeO3 nanocomposites. The photocatalytic amount of SnFe2O4/BiFeO3 nanocomposites was higher than the pristine SnFe2O4 or BiFeO3 nanoparticles. The photocatalytic degradation was mainly performed by OH· radical. The malachite green dye was completely degraded (100%) by using the SnFe2O4-BiFeO3 nanocomposites in 60 min under visible light irradiation. The antibacterial activity of SnFe2O4/BiFeO3 nanocomposites was conducted against Escherichia coli and Bacillus subtilis bacteria. The doxorubicin as an anticancer drug was loaded on SnFe2O4/BiFeO3 nanocomposites. The cell viability of the human liver cancer cell was performed by using doxorubicin/SnFe2O4/BiFeO3/folic acid. The potential properties shows that the usage of SnFe2O4/BiFeO3 nanocomposites in environmental treatment, antibacterial, and drug delivery applications.
