Abstract
Multiwalled carbon nanotube (MWCNT)–polyaniline (PANI) composite films were prepared by in situ electrochemical polymerisation on the titanium sheet from an aniline solution containing a small content of well dispersed MWCNT. Then these composite films were employed as substrate for the electrodeposition of platinum nanoparticles (PtNPs). The morphology of platinum nanoparticle/carbon nanotube-polyaniline composite coatings was characterised respectively by using a scanning electron microscope. The electrochemical behaviour and electrocatalytic activity of PtNPs/PANI–MWCNTs/Ti electrodes for glycerol oxidation were examined and the results show that these modified electrodes are highly active for electrocatalytic oxidation of glycerol.
