The crystallinity, structural, and morphological features were studied by XRD, FE-SEM and UV-Vis diffused reflectance  techniques. The photocatalytic activity of ZnBi<sub>2</sub>O<sub>4</sub>/rGO catalysts were evaluated by degradation of Indigo Carmine dye under visible-light irradiation. The enhancement of photocatalytic properties of ZnBi<sub>2</sub>O<sub>4</sub>/rGO attributed to the synergistic effect between ZnBi<sub>2</sub>O<sub>4</sub> and rGO, which effectively separation of the photogenerated electron-hole pairs in ZnBi<sub>2</sub>O<sub>4</sub>. Moreover, the obtained ZnBi<sub>2</sub>O<sub>4</sub>/rGO displayed high chemical stability after four consecutive experiments under visible light.}, number={5}, journal={Vietnam Journal of Science and Technology}, author={Nha Khanh, Dang Nguyen and Mai Tho, Nguyen Thi and Thang, Nguyen Quoc and Tien, Nguyen Thanh and Phong, Chau Tan and Cang, Mai Quynh and Kim Phuong, Nguyen Thi}, year={2019}, month={Oct.}, pages={572–584} }
