摘要
氧化锌因具有良好的光催化性能,近年来一直受到人们的关注。以CTAB为模板,分别采用化学沉淀法和水热合成法制备氧化锌,使用XRD、FT-IR和SEM对所得产物进行表征和分析,并探究氧化锌光催化降解亚甲基蓝的能力。结果表明:两种方法制得的氧化锌均为六边纤锌矿结构但形貌截然不同,化学沉淀法制得的产品为纺锤型,而水热合成法制得的产品呈花簇状;水热合成法制得的氧化锌对亚甲基蓝降解的催化效果更好。
ZnO has attracted much attention in recent years because of its well photocatalytic properties.In this paper,CTAB as a template,ZnO samples are synthesized by the methods of chemical precipitation and hydrothermal synthesis.The obtained samples are characterized by XRD,FT-IR and SEM,respectively.At the same time,the photocatalytic degradation abilities of the Methylene blue by ZnO are also measured.The results show that the samples of ZnO both have hexagonal wurtzite structures,but with quite different morphologies.The product obtained by chemical precipitation is spindle type;the product obtained by hydrothermal synthesis is flower cluster.ZnO obtained by hydrothermal synthesis has a better catalytic effect on methylene blue degradation.
