| Abstract Scope |
Microbial fuel cells (MFCs) are promising devices for generating sustainable electricity, with the anode playing a crucial role. Electrogenic bacteria in the anodic chamber oxidize organic substrates, releasing protons and electrons, which move towards the cathode via an external circuit, creating an electric current. The use of Fe-MOF/Polyaniline (PANI) as an anode material enhances MFC performance due to Fe-MOF's high surface area and tunable properties, alongside PANI's improved redox activity, stability, and conductivity. Synthesized at room temperature with in-situ polymerized PANI, the Fe-MOF/PANI@GF anode achieved a power density of 277 mW/mē and a high voltage of 319 mV with a 1000-ohm load, outperforming Fe-MOF@GF and unmodified graphite felt. This improved performance is due to reduced charge transfer resistance and increased bacterial affinity, enhancing extracellular electron transfer efficiency. Thus, the Fe-MOF/PANI composite shows promise as an anode material for MFC power generation. |
