Visible-light-assisted photocatalytic removal of methylene blue over ternary ZnO/Zn2SnO4/rGO heterostructures: structural, optical, and charge-transport behavior
Interfacial engineering of semiconductor heterostructures with conductive carbon materials offers a promising strategy for developing visible-light-assisted photocatalysts. In this study, ZnO/Zn2SnO4/rGO (ZSO/rGO) ternary composites with different rGO contents were synthesized via a hydrothermal method. XRD and Raman a...
