Abstract:

Carbon nanotubes (CNTs) have the ability to promote electron transfer reaction when used as electrode materials in electrochemical reaction owing to their high electronic conductivity. The modified glassy electrode coated with multi-walled nanotubes (MWCNTs/GC) is used to detect Electrogenerated Chemiluminescence (ECL) of Ru(bpy)32+ aqueous solution. When the applied potential on the working electrode is at at positive potential of +0.3 V (s. Ag/AgCl), a strong cathodic ECL of Ru(bpy)32+ is observed。This property of MWCNTs/GC is used to examine dopamine (DA) in solution.
