摘要石墨烯是由碳原子以六边形进行排布的二维晶体。是目前已知的最薄的一种材料,并且因为它具有极大的比表面积、超强的导电性和很好的强度等等优点使其拥有良好的市场前景。但是,实际上，石墨烯本身具有一定的褶皱，它不是绝对平整的；而且由于石墨烯也不是天然条件下存在的产物，需要人工制备，而人工制备的石墨烯基于各种制备方法的限制，其结构中也存在各种缺陷，在本论文中，我们以获得制作过程简单、成本低廉、具有较高活性，并且易回收的石墨烯碳复合物为目的，引入以氧化石墨烯(GO)作为组装材料的组装单元，葡萄糖作为连接单元，用一步水热合成法制备了具有超高比表面积的三维石墨烯组装体，并且对所得三维石墨烯组装体的吸附性能进行了进一步的探讨。其主要研究内容如下：81426

通过氧化石墨烯和葡萄糖的结合，形成的石墨烯三维组装体用来吸附罗丹明B溶液，并改变PH值，添加盐溶液和重复使用来测试其吸附性能，结果呈现出：随着溶液浓度的降低，温度的升高和PH值的改变，石墨烯三维组装体的吸附能力都出现变化。

通过本论文的研究，我们进一步认识到由于协同作用的重要性，石墨烯三维组装体不但具有石墨烯良好的固有性质，而且还可能表现出一些新性质。这些新的特性为开发和设计结构新颖、性能优异的石墨烯碳-复合物提供新的思路和新的发展前景。

Abstract Graphene is a two-dimensional crystal that is arranged by carbon atoms in a hexagon。 Graphene is now known to one of the most thin material, and has a great specific surface area, super conductivity and good strength, and so on advantages so that it has good market prospects。 But, in fact, graphene itself has certain wrinkles, which are not perfectly flat; But also because of graphene is not a product of natural conditions exist, need artificial preparation, and preparation of graphene based on all kinds of preparation methods of artificial restrictions, there are all kinds of defects in its structure, in this thesis, we for the production process is simple, low cost, has a highly active, and easy recycling of graphene carbon compounds, for the purpose of the introduction of graphene by oxidation (GO) as an assembly unit assembly materials, glucose as connection unit, using step hydrothermal synthesis method was prepared with high specific surface area of 3 d graphene assembly body, and the obtained 3 d graphene adsorption performance of assembly body has carried on the further discussion。 The main research is as follows: 

Through the combination of graphene oxide and glucose, the formation of graphene 3 d assembly body used for adsorption of rhodamine B solution, and change the PH value, add the salt solution and repeated use to test the adsorption performance, results show: with the loss of the solution concentration, temperature increases and the change of PH value, the adsorption capacity of graphene 3 d assembly body changes。 

Through the research of this paper, we further realize the importance of due to the synergy, graphene 3 d assembly body not only has the inherent properties of graphene is good, but also may show some new properties。 These new features provide new ideas and new development prospects for the development and design of graphene carbon-composites that are novel and well designed。 

Keywords: graphene; adsorbs organic dyes
