dc.description.abstractMicrobial fuel cells (MFCs) offer promising energy generation and pollutant removal solutions. However, instabilities in electrode and organic substrate materials hinder efficient electron transport and generation. This research investigates and compares the performance of commercial plain anodes—graphite (GE), mild steel (ME), and stainless steel (SE)—with graphene derivative coatings synthesized from Nipah palm frond (NPF)—graphene-graphite (GO-GE), graphene-mild steel (GO-ME), and graphene-stainless steel (GO-SE). The electricity generation and pollutant removal performance of the MFCs were monitored over distinct operational periods: 65 days for plain anodes and 105 days for coated anodes. Results show that GO-ME consistently outperforms other anodes, generating 29.10 mW/m2 compared to GO-SE (26.50 mW/m2), GO-GE (7.60 mW/m2), SE (5.85 mW/m2), ME (2.75 mW/m2), and GE (1.07 mW/m2). MFCs demonstrated high bisphenol A (BPA) pollutant removal efficiencies for GO-ME at 98.03%, followed by GO-GE at 96.95%, GO-SE at 83.73%, SE at 96.25%, ME at 94.55%, and GE at 81.08%, with all reactions surpassing over 96% in lead (II) nitrate (Pb(NO3)2) removal efficiency. Nira sap serves as a beneficial organic substrate, fostering Bacillus sp. dominance across all anodes. The research concludes by comparing prior results and suggesting further recommendations.
