将带胺基的双亲柱[5]芳烃(AP5)修饰在还原氧化石墨烯(RGO)表面,得到水分散性RGO-AP5。用AP5做桥联剂,将预先制备的铂纳米粒子(PtNPs:Platinum Nanoparticles)自组装到RGO-AP5表面后得到三元纳米复合材料RGO-AP5-PtNPs。采用TEM、SEM、XRD等手段表征了复合材料的结构和形貌。考查了RGO-AP5-PtNPs中的三组分对客体分子在其修饰电极上的电化学响应的协同促进作用。 The amphiphilic [5] arene (AP5) with amino groups was modified on the surface of reduced graphene oxide (RGO) to obtain water-dispersible RGO-AP5. Using AP5 as a bridging agent, ternary nanocomposites RGO-AP5-PtNPs were obtained by self-assembly of pre-prepared platinum nanoparticles (PtNPs: Platinum Nanoparticles) onto the surface of RGO-AP5. The structure and morphology of the composites were characterized by TEM, SEM and XRD. The synergistic effect of the three components of RGO-AP5-PtNPs on the electrochemical response of guest molecules at their modified electrodes was investigated.
