(a) Unit cell of the ZnGa₂S₄ (ZnGa₂O₄) structure. The blue and green balls represent the Zn and Ga atoms, respectively, while the red ball corresponds to S or O atom. (b) The schematic diagram of the photocatalytic degradation of MB mechanism using ZnGa₂S₄ photocatalysts. Band structures of (c) ZnGa₂O₄ and (d) ZnGa₂S₄ calculated by the HSE06 functional. The Fermi level is set at zero.
