The photocatalytic performance of low-grade Titanium Dioxide (TiO 2 ) anatase was successfully improved by compositing with graphene oxide (GO) via microwave-assisted, activated by UV and Xe light. The various experimental conditions were conducted. X-ray diffraction (XRD), Particle size analyzer (PSA), Prepared TiO 2 /GO photocatalyst was characterized by several instruments such as Specific surface area (BET) and Scanning electron microscopy (SEM). Effect of various annealing times (30 to 120 minutes) and temperatures (200-1000°C) were studied to reach the optimum pure TiO 2  as a further based material in composite with GO. The result showed that both annealing time and temperature influenced crystallinity and particle size only, not the phase structure of TiO 2 . A similar phenomenon was founded by adding GO in a small concentration. A comparison of photocatalytic activity under UV and Xe irradiation has been proposed to show the GO effect independently. Under UV irradiation, the presence of GO enhancing the active sites of the catalyst. 1.0 wt% of GO succeeds in decomposing 8ppm of RhB more than 90%. Meanwhile, under Xe irradiation, the efficiency of the degradation of RhB was only 30%, resulted in using 1.2wt% of GO. Interestingly, the photodecomposition rate ( k ) of TiO 2 /GO composite under Xe irradiation was 3 times over pure TiO 2  higher than that of UV irradiation (1 time). The study present that the small concentration of GO affected not only the active site of the TiO 2 /GO composite but also the electronic properties, which give different effects under different energy activated.
