Abstract

This study investigated the effects of annealing temperature on the structure evolution and antifungal performance of TiO2/Fe3O4 nanocomposites. The TiO2/Fe3O4 nanocomposites were fabricated through a combination of sonochemical and coprecipitation routes. The TiO2 structure evolved from an amorphous phase to a crystalline anatase phase starting at an annealing temperature of 450°C while Fe3O4 evolved to γ-Fe2O3 and α-Fe2O3 starting at an annealing temperature of 600°C. The increases in the crystallite sizes and lattice parameters were also identified because of the increase in the annealing temperature. The TiO2/Fe3O4 nanocomposites tended to agglomerate due to van der Waals forces. The molecular structural dynamics of TiO2/Fe3O4 nanocomposites were also studied by infrared spectroscopy within the wavenumber range of 400-4000cm-1. The antifungal activity of TiO2/Fe3O4 nanocomposites was better than those of individual TiO2 and Fe3O4. These results showed that structure evolution plays an essential role in the antifungal performance of TiO2/Fe3O4 nanocomposites.
