Abstract: Magnetically separable TiO2-graphene oxide nanocomposites (Fe3O4/TiO2/GO0.10) and magnetically TiO2 nanocomposites (Fe3O4/TiO2) were successfully synthesized by coprecipitation method. As prepared Fe3O4/TiO2/GO0.10 and Fe3O4/TiO2 were characterized by SEM-EDS, FTIR, XRD, TG, specific surface area and pore size analysis. The photocatalytic efficiency of Fe3O4/TiO2/ GO0.10 and Fe3O4/TiO2 were evaluated using the degradation of acridine orange. The effect of pH, time, ultraviolet and recycle on photocatalytic performance of Fe3O4/TiO2/GO0.10 and Fe3O4/TiO2 were studied. Fe3O4/TiO2/GO0.10 is better than Fe3O4/TiO2 for the degradation of acridine orange under visible light and ultraviolet light. This is mainly because the addition of GO can improve the photocatalytic performance of Fe3O4/TiO2/GO0.10. Fe3O4/TiO2/GO0.10 exhibited reasonably good photocatalytic efficiency after three cycles. Fe3O4/TiO2/GO0.10 can be used as a recyclable catalyst for the removal of acridine orange.
