Facile synthesis of SiO2/RGO composite for the adsorption of Rhodamine B

doi:10.16085/j.issn.1000-6613.2017-1219

Abstract

Abstract: SiO₂/RGO composite was synthesized without any reductant by hydrothermal method with tetraethyl orthosilicate(TEOS) and GO as the starting raw. The microstructure and physiochemical properties of the SiO₂/RGO composite were characterized by TEM,FTIR,XRD,TG-DSC and N₂-adsorption. The results showed that the SiO₂ nanoparticles were uniformly distributed on the surface of RGO,and some SiO₂ nanoparticles coordinated with RGO via Si-O-C bonds. The optimized composite contained 76.60% SiO₂ and possessed micro-mesoporous structure with pore size distribution of 1-7nm and surface area of 676m²/g. In addition,the influences of pH,dosage,temperature and contact time on the adsorption of Rhodamine B were studied systematically. The highest adsorption capacity reached 127.8mg/g under the optimized conditions(pH of 2 and 35℃). Kinetic analysis showed that the adsorption process could be well described by the second-order law and the process was endothermic.

摘要： 以正硅酸乙酯（TEOS）为硅源，氧化石墨烯（GO）为载体，在不添加任何还原剂的情况下，通过水热法简易制备SiO₂/还原氧化石墨烯（SiO₂/RGO）复合材料。采用TEM、FTIR、XRD、TG-DSC、N₂-吸附对复合材料的微观结构进行表征，分析表明：负载量为76.60%（质量分数）的SiO₂纳米颗粒均匀分散在RGO表面上，且部分以Si-O-C键进行配位；具有多级孔结构的SiO₂/RGO复合材料孔径主要分布在1~7nm，比表面积高达676m²/g。以罗丹明B为目标污染物，考察了pH、投入量、温度和接触时间等因素对复合材料吸附性能的影响，结果表明：在pH为2、35℃时，复合材料具有最佳的吸附效果，吸附量为127.8mg/g。动力学分析表明吸附过程符合准二级动力学模型，热力学参数揭示吸附过程为自发吸热过程。
