Abstract

An air-cathode microbial fuel cell (MFC) was implemented to examine the cathode material: bismuth ferrite (BFO) nanoparticles mixed with carbon soot. The physicochemical characterization of prepared carbon soot showed that the carbon soot particles were porous and graphitic consisting of 88% carbon. The physicochemical characterization of BFO confirms that the nanoparticles are spherical, have a high surface area, and are electrochemically active. Based on the results of the linear sweep voltammetry (LSV) examination, the large surface area of BFO has been accounted for by high ORR (oxidation–reduction reaction) activities. The increasing loading rates of BFO (0.25–1 mg/cm²) showed increasing power output, with 1 mg/cm² achieving the maximum power density and current density (11.99 W/m³ and 35.45 A/m³, respectively), which were comparable to the power output of platinum. According to electrochemical impedance spectroscopy (EIS) analysis, BFO showed the lowest resistance (R _ct) across each electrode transmission (39.5) at a loading rate of 1 mg/cm². This low R _ct value indicates that the cathode catalyst facilitates high electron transfer, thereby increasing the cathode's ORR activity. The cathode biofouling analysis for different concentrations of BFO conducted via confocal laser scanning microscopy (CLSM) showed that 1.0 mg/cm² BFO showed the least biofouling. The results of the research suggest that BFO-blended carbon soot has potential as a cost-effective alternative for field-scale usage.
