Carbon nanotube/polypyrrole nanocomposite as a novel cathode catalyst and proper alternative for Pt in microbial fuel cell
This study demonstrates the use of carbon nanotube polypyrrole (CNT/PPy) nanocomposite as a novel cathode catalyst in microbial fuel cells (MFC). The CNT/PPy nanocomposite has been prepared using a chemical oxidative method and its performance in MFC was evaluated and compared with platinum, the...

description |
This study demonstrates the use of carbon nanotube polypyrrole (CNT/PPy) nanocomposite
as a novel cathode catalyst in microbial fuel cells (MFC). The CNT/PPy nanocomposite
has been prepared using a chemical oxidative method and its performance in
MFC was evaluated and compared with platinum, the traditional cathode catalyst. The
attachment of microorganisms on the anode was confirmed using field emission scanning
electronic microscopy (FESEM) analysis. The size of ppy nanoparticles was also observed
using SEM. Cyclic voltammetry (CV) studies were done to investigate the catalytic properties
of CNT/PPy nanocomposite. The maximum power density and coulombic efficiency
attained by the usage of CNT/PPy nanocomposite was found to be ~113 mW/m2 and 21%
respectively, which is a significant comparison with the Pt catalyst, where the measured
values were 122.7 mW/m2 and 24.6% respectively. The COD removal of both systems was
found to be more than 80%. The results indicate that CNT/PPy nanocomposite could be
used as a possible lower cost alternative than Pt catalyst in MFC. |
