| Abstract: | The electrochemical detection of one of the most sought after analytical targets has been studied at single-walled carbon nanotube ensemble networks, which are electrically wired via an underlying electrode substrate. A range of parameters and their effect on the electro–analytical detection of hydrogen peroxide have been explored which includes heterogeneity, role of the underlying electrode, electrode pre-treatment and analytical performance. This work provides researches with an overall view of the various parameters, which may affect the electro–analytical detection of hydrogen peroxide at native carbon nanotubes before modification with electro–catalytic materials allowing the assignment of the true origin of electro–catalysis to be properly assigned. |
