摘　　要：采用水浴法简单的调节pH值合成了ZnO-Zn(OH)2复合材料。利用XRD、SEM、光电流测试等手段对合成的样品进行表征,以确定样品的晶体结构、形貌和载流子寿命等特性。对水中罗丹明B污染物进行降解,研究其光催化活性。结果表明,ZnO-Zn(OH)2样品在180 min内降解了77.02%的罗丹明B,具有最佳的光催化活性。ZnO-Zn(OH)2 composites were synthesized by adjusting the pH with a water bath method.In order to explore the crystal structure,morphology,and carrier lifetime characteristics of the materials,the synthesized materials were characterized by XRD,SEM,and photocurrent.To further study the photocatalytic activity,this experiment degraded rhodamine B pollutants in water.The results show that the ZnO-Zn(OH)2 heterojunction material has the best photocatalytic activity,degrading 77.02%of rhodamine B within 180 min.
