The photodegradation of Congo red (CR) dye was studied with pure Cu2O, Cu2O/TiO2 (CT), and Cu2O/ZnO (CZ) heterojunctions photocatalysts. A facile one-pot solvothermal method with absolute ethanol as a solvent and reducing agent was used to prepare the photocatalysts. CT and CZ showed excellent adsor...
