Size-Dependent Chlorinated Nitrogen-Doped Carbon Nanotubes: Their Use as Electrochemical Detectors for Catechol and Resorcinol

Figure 6

Cyclic voltammogram recorded at a bare GCE, chlorinated N-doped CNTs (1 : 2)/GCE, and chlorinated N-doped CNTs (2 : 1)/GCE at a scan rate of 50 mVs⁻¹ in 0.1 M PBS of pH 7.2 containing (a) 0.5 mM CC and (b) 0.4 mM RS.
