Two-Dimensional Heterostructure of PPy/CNT- for High-Performance Supercapacitor Electrodes.

The nano-biocomposite electrodes composed of carbon nanotube (CNT), polypyrrole (PPy), and -bacteria were investigated for electrochemical supercapacitors. For this purpose, PPy/CNT- was successfully synthesized through oxidative polymerization. The PPy/CNT- electrode exhibited a high specific capacitance of 173 F∙g at the current density of 0.
