摘　　要：传统的二维氧化石墨烯存在比表面积小、降解效率低、肉眼难以分辨的缺点,本文以改进的Hummers法制备的GO为前驱体,利用模板法,将GO包裹在三维模板聚苯乙烯微球上,去除模板得到三维多孔石墨烯,并以其作为吸附剂对亚甲基蓝进行吸附去除反应,评价吸附剂对亚甲基蓝的降解性能。研究结果表明:三维多孔石墨烯在60 min时,MB降解率能达到99%,是二维氧化石墨烯的3倍以上,因此,通过将二维材料三维化,可以使材料吸附性能大幅提高,为研发新型吸附剂提高新的可能性。Traditional two dimensional graphene oxide is small in specific surface area,low in degradation efficiency,and difficult to discern with the naked eye.In this study,with the GO prepared by the improved Hummers method as the precursor,the template method was used to coat GO on the three dimensional template polystyrene microspheres,and with the template removed the Three Dimensional Porous Reduced Ggraphene Oxide was obtained,which was then used as an adsorbent to adsorb and remove methylene blue.Finally,its ability to degrade methylene blue was evaluated.The results show that the MB degradation rate by 3DPrGO can reach 99%when they react for 60 min,which is more than three times that by two dimensional graphene oxide.Therefore,by making the two dimensional material three dimensional,its adsorption performance can be greatly improved.This study offers new possibilities for the development of new adsorbents.
