摘要：自2004年石墨烯单片层被发现以来，由于其极好的导电、导热能力以及优越的机械强度、超高的载流子速度，被认为是未来性能极为优越的未来材料，能够在电子学、太阳能电池、能源存储等方面得到广泛应用。化学方法还原氧化石墨烯被普遍认为是一种操作简便、成本较低、可进一步探索成为大量制备石墨烯的一个有效方法，同时对于量产还有追求安全、环保的工艺过程。本文，基于化学还原氧化石墨烯制备石墨烯的工艺条件下，对绿色的混合碱还原氧化石墨烯和柠檬酸钠还原氧化石墨烯进行最优工艺的研究。主要研究如下，对于混合碱还原氧化石墨烯，探究不同的碱比例、反应时间、反应温度对产物质量的影响，寻找最优的实验条件；对于柠檬酸钠还原氧化石墨烯，探究不同的反应温度、反应时间对产物质量的影响。通过X射线衍射（XRD）、红外光谱（FT-IR）、扫描电镜（SEM）等检测手段对产物及产物质量进行了表征测试。实验结果显示，混合碱还原氧化石墨烯的方法优于柠檬酸钠还原氧化石墨烯的方法。31496

The reduction of graphene oxide
Abstract: Since the year of 2004, the monolithic layer graphene was discovered,it has been considered to be the future of future performance is extremely superior material for its excellent electrical conductivity, thermal conductivity and excellent mechanical strength, high carrier velocity. And it is considered to be widely used inelectronics , solar cells, energy storage, etc. area.The synthetic method of chemically reduced graphene oxide is generally regarded as a simple, low cost, and an effective way to further explore the mass production of graphene. While the safe and environmentally friendly production processes is our common pursuit. In this paper, based on the following chemical reduction of graphene oxide graphene preparation process is under following two conditions, reduction of green mixed alkali graphene oxide and sodium citrate reducing graphene oxide to study the optimal process.The main research is as following, for mixed alkali reducing graphene oxide to explore different base sratio, reaction time and reaction temperature on the quality of the product, and to find the optimal experimental conditions; sodium citrate for the reduction of graphene oxide, explore different reaction temperatures , reaction time on product quality. The quality and characterization of the product has been tested by X-ray diffraction (XRD), infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and other detection means. Experimental results showed that the mixed alkali reducing graphene oxide is superior to sodium citrate reduction method of graphene oxide. But the use of mixed alkali reduction of graphene oxide product obtained still have deficiencies. We should continually improve the program, and find better ways to achieve mass production industrial applications.
