Flexible graphene oxide−wrapped SnO2 hollow spheres with high electrochemical sensing performance in simultaneous determination of 4−aminophenol and 4−chlorophenol

Flexible graphene oxide−wrapped SnO2 hollow spheres with high electrochemical sensing performance in simultaneous determination of 4−aminophenol and 4−chlorophenol
Graphene oxide−wrapped hierarchical hollow structured SnO2 spheres were fabricated by hydrothermal strategy and applied to the sensitive electrochemical sensing of phenolic compounds. The as−prepared new nanocomposite modified electrode characterized by morphology, X−ray diffraction, Raman spectroscopy, electrochemical impedance, and electroactive surface area suggested its efficiency for the individual and simultaneous sensing of 4−aminophenol (4−AP) and 4−chlorophenol (4−CP), exhibiting as the remarkable increase in peak currents compared with SnO2 or graphene oxide modified electrodes. After optimization of electrochemical parameters, the detection limits of 2.2nM for 4−AP and 3.1nM for 4−CP were obtained using differential pulse voltammetric method. Finally, the application of the modified electrode in real water samples was evaluated, indicating that it could be used as an excellent platform for the detection of phenolic pollutants.
