RGO／ZnO 纳米棒复合材料的合成及光催化性能
Synthesis and Photocatalytic Performance of RGO/ZnO Nanorod Composites
摘要
Abstract
ZnO nanorods and RGO/ZnO nanorods composites were prepared by hydrothermal method . The influence of RGO content on the photocatalytic activity of RGO/ZnO nanorods composites was studied . ZnO nanorods and RGO/ZnO nanocomposites were characterized by X‐ray diffraction (XRD) ,field emission electron microscopy (FESEM ) ,X‐ray photoelectron spectroscopy (XPS) and diffuse reflectance UV‐visible absorption spectroscopy techniques .The results show that RGO/ZnO samples are synthesized successfully .With different additions of GO ,the RGO/ZnO samples obtained exhibit different absorption characteristics in visible light region .The photocatalytic results of using methyl orange (MO) as the simulated pollutant show that RGO/ZnO nanorods composites exhibit high degradation efficiency under UV‐Vis light illumination .The highest photocatalytic performance is obtained for RGO/ZnO composites w hen the mass ratio of RGO to ZnO is 3% .M O is almost com‐pletely degraded in 120min .RGO/ZnO also shows the visible‐light‐driven photocatalytic activity under visible light illumination (λ> 400nm) ,and the maximum MO degradation efficiency in 180min can reach 26 .2% ,meanwhile ,RGO/ZnO samples exhibit good photostability .关键词
