【Abstract】 The photocatalytic activities of ZnO,Co₃O₄,ZnCo₂O₄,the physical mixture of ZnO and Co₃O₄ and the simple chemical complex oxide which are fabricated with citric acid have been researched.The photocatalytic activities of ZnCo₂O₄ that are calcined at different temperatures have also been researched.The result reveals that the sequence of the photocatalytic activity are physical mixture>simple chemical complex oxide>single oxide>spinel oxide.The photodegradation rate with the physical mixture oxide could reach 100% when the dosage of photocatalyst is 150 mg and the concentration of reactive dyestuff is 20 mg/L.更多还原
