Abstract

Graphene oxide-templated polyaniline (GO-PAN) microsheets were prepared via oxidation polymerization of aniline with graphene oxide (GO) as template. By applying this approach, irregularly shaped GO-PAN microsheets were obtained which was revealed by scanning electron microscopy (SEM). Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) measurements demonstrated that the resulted GO-PAN was electroactive and could be further used as electrocatalyst in simultaneous determination of ascorbic acid (AA), dopamine (DA) and together with uric acid (UA).
