中文摘要：

以醋酸锌和膨胀石墨为原料, 采用真空辅助压力诱导手段使反应溶液注入膨胀石墨层间, 在180℃下溶剂热反应12 h, 一步得到氧化锌纳米棒/石墨烯复合光催化剂, 采用X射线衍射仪（XRD）和透射电子显微镜（TEM）等对复合光催化剂的结构和形貌进行了表征. 结果表明, 合成的氧化锌纳米棒具有六方晶系纤锌矿结构; 氧化锌纳米棒在石墨烯表面分散性较好, 其平均直径约50 nm, 长度约150~200 nm. 所得氧化锌纳米棒/石墨烯复合材料对亚甲基蓝的降解效率优于目前应用最广泛的光催化剂Degussa P25.

英文摘要：

Zinc acetate and expanded graphite were selected as raw material. Under vacuum, the initial reaction solution was infused in the interlayers of expanded graphite. Then, zinc oxide nanorods/graphene compo-sites were prepared by solvothermal method at 180℃ for 12 h. The structure and the morphology of ／{products were characterized by X-ray diffraction（XRD） and transmission electron microscopy（TEM）. The results show that the zinc oxide nanorods uniformly grow on the surface of graphene sheets. The average diameter of rod-like zinc oxide is about 50 nm, and the length is about 150-200 nm. The zinc oxide nanorods/graphene compo-sites exhibited high photocatalytic activity in the degradation of methylene blue under UV lights in comparison with bare Degussa P25.
