Graphene Oxide‐Templated Polyaniline Microsheets toward Simultaneous Electrochemical Determination of AA/DA/UA

Abstract

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).
