| 摘 要： | 分别加热醋酸锌和水洗后的可膨胀石墨、干燥后的可膨胀石墨和膨胀石墨(EG)的混合物,制备了3种不同的膨胀石墨/ZnO复合材料,分别记为EG/ZnO-1,EG/ZnO-2和EG/ZnO-3.使用X射线衍射分析(XRD)、扫描电子显微镜(SEM)和Branaucr-Emmett-Teller(BET)比表面积等技术对样品结构进行表征.在紫外线(UV)照射下,研究了EG/ZnO对水中亚甲基橙的去除效率.结果表明,EG/ZnO同时具有膨胀石墨的吸附功能和ZnO的降解功能.在3种EG/ZnO中,EG/ZnO-3对水中甲基橙的去除效率最高.使用EG/ZnO-3,甲基橙去除率受EG/ZnO-3热处理温度和ZnO含量的影响.在优化工艺条件下,经过3.5hUV照射,水中甲基橙可被完全去除. |

| Abstract: | Three exfoliated graphite (EG) doped with ZnO,marked as EG/ZnO-1,EG/ZnO-2 and EG/ZnO-3 composites,were prepared by heating a mixture of zinc acetate with water-washed expansible graphite,dried expansible graphite and EG,respectively. The composites were characterized by XRD,SEM and Branauer-Emmett-Teller (BET). Under UV irradiation,the removal of methyl orange (MO) from aqueous solution with the composites was investigated. The experimental results showed that the composites could synchronously provide with... |
