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...

description |
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 microbial fuel cell (MFC). The physical and electrochemical characterization of PVP-MnO2/CNT were performed by using Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray analysis (EDX), X-ray Diffraction analysis (XRD), Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). The electrochemical characterization results showed that the PVP-MnO2/CNT possessed the higher ORR catalytic activity with lower charge transfer resistance compared to MnO2 and MnO2/CNT. The performance of the electrocatalysts as
cathode was evaluated in air-cathode MFC and it was found that the MFC with MnO2-PVP/CNT electrocatalyst generated a maximum power density of 1365.30 mW/m3, which was higher than that of MFCs with MnO2/CNT catalyst (1083.98 mW/m3), MnO2 (540.91mW/m3) and CNT (438.47 mW/m3). Therefore, the viable synthetic strategy and proposed application of PVP-MnO2/CNT will broaden up the reality of MFC for power generation. |
