Graphite oxide was prepared through hydrothermal synthesis method. Then the graphite oxide was scattered by ultrasound together with titanium dioxide, after which graphite oxide was reduced into graphene through hydrozine hydrate reducing method and UV reducing method, respectively. The two samples were tested by scanning electron microscope (SEM), the ultraviolet spectrometer (UV), X-ray diffraction (XRD), thermogravimetric analysis (TGA). By using P25 as photo-anode electrode, I-/I3-as the electrolyte solution, P25 covered with the prepared sample, the DSSC batteries were assembled. The electrochemical properties of the batteries were tested under different lights, such as blue, green, white, UV-light and simulated sunlight. Experimental results showed that the graphene prepared by hydrozine hydrate reducing method possessed good photo-electrochemicial performance.
