摘要
以柠檬酸为Zn2+络合剂,采用液相沉淀法制备ZnO纳米粉体。利用XRD、TEM等测试手段对样品的结构和形貌进行表征。结果表明:所得纳米ZnO属于六方纤维矿的单晶结构,平均粒径为10nm。以纳米ZnO悬浮体系对有机磷农药氯胺磷进行光催化降解研究,考察了催化剂用量、光源及溶液的pH值等因素对光催化降解效果的影响。
ZnO nanoparticles were synthesized by a precipitation method with citric acid as the complexing agent. The characterizations of ZnO nanoparticles were carried out by XRD and TEM. The results show that as-prepared ZnO crystals are single crystals with a hexagonal quartzite structure. ZnO nanoparticles are uniform with 10 nm in diameter. The photo catalytic degradation of chloramines phosphorus was studied in the suspension system of ZnO nanoparticles, the influence of the amount of ZnO, light sources and original pH of solution were investigated.
