Graphene-Multiwalled Carbon Nanotube Hybrids Synthesized by Gamma Radiations: Application as a Glucose Sensor
Figure 8
(a) CVs of bare GC electrode and that modified with GO, f-MWCNTs, G-MWCNTs (3 : 1), G-MWCNTs (1 : 1), and G-MWCNTs (1 : 3). The experiments were carried out in 5.0 mM K3[Fe(CN)6] containing 1.0 M KCl and the potentials were applied versus Ag/AgCl reference electrode at a scan rate of 100 mVs−1. (b) Amperometric responses of GC, GO, f-MWCNTs, and G-MWCNTs modified electrodes for successive addition of glucose concentrations (0.1–18 mM) at an applied potential of +0.6 V, versus Hg/HgO in 0.1 M NaOH.
