Graphene oxide (GO) is a pH-dependent amphiphile. In this paper, it was found that carbon nanotubes (CNTs) can be highly dispersed in graphene oxide “water” with the aid of prototype ionic liquid of 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF 6 ]). The introduction of [BMIM][PF 6 ] not only can minimize the defects of poor electrical conductivity of GO, but also can...
In the present work, a novel strategy based on new carbon nanotube (CNT) and polypyrrole (ppy) composite modified electrode for the simultaneous determination of the isomers of Amaranth (E123) and Ponceau 4R (E124) was proposed. Due to the increasing dispersibility and effective surface area of the CNT caused by decoration of ppy to the CNT, the proposed electrode exhibited excellent electrochemical...
