MnO2/CNT as ORR Electrocatalyst in Air-Cathode Microbial Fuel Cells

MnO2/CNT as ORR Electrocatalyst in Air-Cathode Microbial Fuel Cells

Air-cathode microbial fuel cell (MFC) is a potential electrochemical device for green power generation simultaneously conducting wastewater treatment. In the present work, the MnO2 catalyst has been prepared and modified by inducing carbon nanotube (CNT) via sonochemical-coprecipitation method. The...
