【摘要】：石墨烯(Graphene,G)是由类似苯环结构组成的蜂窝状二维晶形结构,具有大的比表面积和共轭体系,是一种优良的吸附剂。但G化学稳定性极好,几乎不溶解;另外,层与层之间强大的π-π共轭作用,致使其易在水或有机溶剂中发生聚集,不利于其本身特性的展现。将G与其它材料复合,不仅可以改善G的分散性,而且可以赋予复合材料一些新的特性。该文综述了近年G复合材料的制备方法及其作为吸附剂在吸附环境污染物中的研究进展,对吸附机理进行了简述,并对G复合材料作为吸附剂的发展趋势进行了展望。
[Abstract]:Graphene Graphene G) is a honeycomb two-dimensional crystal structure with large specific surface area and conjugated system, which is a kind of excellent adsorbent. However, G has excellent chemical stability and is almost insoluble. The strong 蟺-蟺 conjugation between layers makes it easy to aggregate in water or organic solvents, which is not conducive to the display of its own properties. Combining G with other materials can not only improve the dispersion of G. In this paper, the preparation methods of G composite materials and their research progress as adsorbent in adsorption of environmental pollutants are reviewed, and the adsorption mechanism is briefly described. The development trend of G composite as adsorbent is also prospected.
