A novel multiwall carbon nanotubes (MWCNTs) modified carbon ionic liquid electrode
(CILE) was fabricated and used to investigate the electrochemical behavior of
norepinephrine (NP). MWCNTs/CILE was prepared by mixing hydrophilic ionic liquid, 1-
methyl-3-butylimidazolium bromide (MBIDZBr), with graphite powder, MWCNTs, and liquid
paraffin. The fabricated MWCNTs/CILE showed great electrocatalytic ability to the oxidation
of NE. The electron transfer coefficient, diffusion coefficient, and charge transfer resistant ( ...
