Abstract
Keggin-type heteropolyanion doped composite of polyaniline (PANI/PMo12), and of polyaniline/multi-walled carbon nanotubes (PANI/PMo12/MWCNTs) was fabricated by electrochemical polymerization with ITO electrodes. The addition of multi-walled carbon nanotubes made heteropolyanions distributing evenly in the hybrid structure. PANI/PMo12/MWCNT composite showed more strong electrochemical activity than PANI/PMo12 composite material. Electrocatalytic studies indicated that PANI/PMo12/MWCNT composite has good electrocatalytic activities towards the reduction of IO3−.
