Abstract: In this research, titanium dioxide/graphene oxide thin lms at different concentration of graphene oxide
(0.0, 0.015, 0.030, 0.045 and 4.5 g/mL) were prepared by spin coating method. Characterization of the samples was
performed using X-ray diffraction and eld emission scannig electron microscope and atomic force microscope. X-ray
diffraction results showed that by adding the graphene oxide, the peak associated with (001) reection was observed
at the angle of 10.5°. The analysis of energy dispersive X-ray also conrmed the formation of graphene oxide sheets.
Considering the excellent photocatalytic and antibacterial properties of titanium dioxide, the effect of adding different
concentration of it on these properties has been investigated. The results showed that the presence of graphene oxide
increases the inhibition of Escherichia coli bacterial growth.
