Synthesis of lamellar O-doped ZnIn2S4 on layered g-C3N4 for boosted charge transfer and photocatalytic performances

The formation schematic is representative of the CN/O-doped ZIS composite. First, the pure g-C 3 N 4 powder was prepared by directly calcining melamine in a muffle furnace. Then CN/O-doped ZIS composites were prepared via hydrothermal method.
