| 摘 要： | 采用一步法制备结构均一的六棱柱状Au-ZnO复合纳米材料,并通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)等对其结构和形貌进行表征.结果表明,改变HAuCl4的用量能够很好地调控所合成的纳米复合物的形貌.在此基础上,研究了Au-ZnO纳米颗粒的光催化性能,当Au含量为2.65%时,所合成纳米复合物对罗丹明B染料的光降解能力最佳,降解率达到99.6%.

| Abstract: | In this paper ,uniform hexagonal prism Au‐ZnO nanocomposite was successfully synthesized by one‐step reaction .The structure and morphology of Au‐ZnO nanocomposite were characterized using XRD , TEM , SEM , respectively . The results show that the morphology of Au‐ZnO could be controlled by changing the amount of HAuCl4 . On the basis ,the photocatalytic performance of the Au‐ZnO nanocomposite was investigated .When the content of the Au was 2.65% ,the efficiency of photocatalytic degraded rhodamine B was the best ,and the degradation rate could reach 99.6% . |
