Facile Synthesis of PVP-MnO2/CNT Composites as ORR Electrocatalyst for an Air-Cathode Microbial Fuel Cell

The cathodic oxygen reduction reaction (ORR) is an influential step in fuel cells for the electrochemical energy conversion. Here we synthesized Polyvinylpyrrolidone incorporated carbon nanotube supported manganese dioxide (PVP-MnO2/CNT) composite and used as ORR electrocatalyst for air-cathode micr...
