回流法制备纳微棒簇氧化锌的结构与光催化性能

Structure and Photocatalytic Activity of Nano-micro ZnO Rod Clusters Synthesized by Reflux Method

以Zn(CH_3COO)_2·2H_2O和氨水为原料,采用回流法,在不额外添加任何分散剂条件下制备纳微结构的ZnO棒簇。利用SEM、XRD和EDS等手段对产品的形貌和结构进行了表征。进一步研究了所制ZnO棒簇降解有机物亚甲基蓝的光催化性能。实验结果表明,在可见光照射时间为180 min后,所制纳微结构ZnO棒簇对亚甲基蓝的降解率可达96.7%。

Nano-micro ZnO rod clubclusters was prepared without any surfactants via reflux method using Zn（ CH3COO）2·2H2O and NH3· H2O as raw materials. The samples were characterized by SEM,XRD and EDS. Photocatalyst of methylene blue（ MB） in aqueous solution was investigated by using nano-micro ZnO rod clubclusters as photocatalyst. The results show that the degradation rate of methylene blue could reach to 96. 7% after 180 minutes under visible-light irradiation.
