Abstract:
In this study, cyclic voltammetry, potential step chronoamperometry, batch amperometry,
hydrodynamic voltammetry and electrochemical impedance spectroscopy were used to
investigate the physical and chemical properties of glassy carbon macro-electrodes
modified using HiPCo® single-walled carbon nanotubes. The latter were themselves
characterised using atomic force microscopy, infrared and Raman spectroscopy and
thermo-gravimetric analysis. The electrochemistry of redox-active functionalities present
on the nanotube surface was probed. The modified electrodes were used to determine
ferrocyanide, dopamine, epinephrine, norepinephrine, ascorbic acid, NADH, oxygen and
hydrogen peroxide. Comparisons between the electro-catalytic properties of nanotubes
and conventional graphite were also performed. The suitability of a number of different
solvents for the dispersion and casting of nanotubes was evaluated.
