摘要
三维石墨烯具有的三维多孔结构不仅有利于反应物和电解质扩散,还可以为电荷的快速转移和传导提供独特的导电通路,因此在超灵敏传感器构筑中具有潜在的应用价值。本文基于三维石墨烯/SDBS半胶束复合纳米材料构建了铅离子电化学传感器。复合材料结合了三维石墨烯的三维大孔结构、高电导率、高比表面积的优势以及SDBS半胶束对铅离子的富集和沉积作用,利用阳极溶出伏安法测定铅离子时检出限为0.0145nM。以上结果不仅为设计简单、高灵敏度的重金属离子电化学传感器提供了新思路,也为在两亲性分子辅助下构建具有多功能的三维石墨烯复合纳米材料提供了新途径。
A novel heavy metal ion electrochemical sensor based on 3D Graphene/sodium dodecyl benzene sulfonate hemimicelles was developed.This electrochemical sensing interface exhibited excellent stripping performance for the analysis of Pb~(2+) with the detection limit of 0.0145 nM,combining the advantageous of 3D graphene foam together with the unique accumulating features of hemimicelle.Our investigation might not only initiate new opportunities for the development of a facile,portable,highly sensitive electrochemical sensor of heavy metal ion,but also pave a new way for constructing 3D graphene-based materials with wider catalytic performance and higher stability under ionic surfactant assistance.
