摘　　要：以Zn(NO3)2.6H2O和Na2CO3为原料、十二烷基苯磺酸钠为分散剂,采用低温固相法在350℃下制得纳米ZnO。通过XRD物相分析,发现ZnO纳米粒子样品的物相为六方晶系纤锌矿结构;TEM形貌观察,粒子基本为球形,添加表面活性剂的ZnO的平均粒径约为20 nm。水溶液中次甲基蓝染料在ZnO半导体光催化条件下、pH为9时,降解90 min,降解率达到56%。Nanosized ZnO was prepared at 350℃ by solid state method using zinc nitrate and sodium carbonate as raw material and sodium dodecylbenzenesulfonate as dissolvent. The morphology and structure were characterized by XRD and TEM analyses. When the pH was 9, by the photocatalysis of nanosized ZnO for 90 rain ,the degraded rate of methylene blue in water solution could achieve 56%.
