Abstract

Graphene oxide nanoribbons (GONRs) have abundant oxygen-containing functional groups and exhibit the improved dispersibility and biocompatibility. Unzipping of multi-walled carbon nanotubes (MWCNTs) was used for the fabrication of GONRs in this work. A glassy carbon electrode modified with GONRs and gold nanoparticles, GCE/GONRs−AuNPs, was prepared via a two-step approach and it exerted a high catalytic activity for the electrochemical oxidation of SO32− and NO2. Under the optimum experimental conditions, the sensitive electrochemical detection of SO32− and NO2 was realized. The developed sensor exhibited a good selectivity, excellent reproducibility, satisfactory stability and high accuracy.
