Preparation of New MFC Anode and Degradation Performance of Ship's Oily Waste Waterv

Microbial fuel cells (MFCs) have emerged as a promising technology for sustainable energy production and environmental remediation, particularly in treating oily wastewater in the maritime industry. However, their practical application has been limited by low power output and energy conversion efficiency. Research has explored enhancing MFC power output through anode modification and electrode material optimization, with biochar showing potential as an alternative anode material. Our study developed pine cone biochar as an anode for MFCs, demonstrating excellent biocompatibility and significantly improved power generation and degradation performance. FT-IR, contact angle measurements, and electrochemical techniques characterized the MFC performance, with biochar-based MFCs achieving higher voltage, power output, and current density compared to carbon felt. Additionally, biochar MFCs exhibited a higher oil wastewater degradation rate and COD removal efficiency. These findings suggest that biochar is a promising anode material for MFCs, warranting further research to optimize MFC design and operational conditions for effective wastewater treatment and energy recovery.
