Carbon Nanotube/Pt Cathode Nanocomposite Electrode in Microbial Fuel Cells for Wastewater Treatment and Bioenergy Production

In this paper, we reported the fabrication, characterization, and application of carbon nanotube (CNT)-platinum nanocomposite as a novel generation cathode catalyst in microbial fuel cells (MFCs) for sustainable energy production wastewater treatment. The efficiency nanocomposites was compared by platinum (Pt), which is most effective common catalyst. This utilized to benefit from catalytic properties CNTs reduce amount required Pt, it an expensive CNT/Pt were synthesized via chemical reduction technique electrodes characterized field emission scanning electron microscopy, electronic dispersive X-Ray analysis, transmission microscopy. applied catalysts MFC obtain polarization curve coulombic (CE) results. tested linear sweep voltammetry. at concentration 0.3 mg/cm2 had highest performance terms CE (47.16%), internal resistance (551 ?), COD removal (88.9%), power (143 mW/m2). contrast, electrode with 0.5 mg/L Pt catalyst, CE, resistance, removal, 19%, 810 ?, 96%, 84.1 mW/m2, respectively. So, has been found that better clean MFC.
