| 摘 要： | 为了拓展石墨烯凝胶材料在污水处理领域的应用，以氧化石墨烯与氢氧化铜为前驱物，氨水为氮源，葡萄糖为还原剂，利用一步水热法制备了氮掺杂石墨烯/氧化亚铜（NG/Cu2O）复合凝胶材料。采用X射线衍射仪、扫描电子显微镜表征产物的微观形貌与结构，通过紫外-可见分光光度计测试NG/Cu2O复合材料在不同的光照环境下对罗丹明B（RhB）染料所表现出的吸附降解性能。实验结果表明，与NG凝胶相比，NG/Cu2O复合凝胶材料表现出更好的吸附与催化降解能力，且在紫外光的光照环境下对RhB染料的吸附降解性能最佳。

| Abstract: |
To expand the application of graphene hydrogel in waste water treatment，an efficient one-step hydrothermal method was developed for the synthesis of nitrogen-doped graphene/cuprous oxide （NG/Cu2O） composite hydrogel using graphene oxide and Cu（OH）2 as the precursors，ammonia as the nitrogen source，glucose as the reducing agent. Scanning electron microscopy and X-ray diffraction were conducted to characterize the morphology and structure of the composites. The adsorption/degradation properties for Rhodamine B（RhB） of NG/Cu2O composite hydrogel were evaluated by ultraviolet-visible spectrophotometer. The experimental results showed that compared with NG hydrogel，the NG/Cu2O composite hydrogel possessed better adsorption/degradation ability for RhB，especially under UV light irradiation. |
