摘　　要：研究了柠檬酸法制备的ZnO和Co_3O_4的单一氧化物,物理、简单化学复合氧化物和尖晶石型ZnCo_2O_4的光催化性能,及不同煅烧温度下ZnCo_2O_4的光催化活性。结果表明,催化活性顺序为物理复合氧化物>简单化学复合氧化物>单一氧化物>尖晶石型复合氧化物,150 mg物理复合氧化物对20 mg/L染料的光催化降解效率可达100%。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.
