Abstract

The use of traditional fossil fuel energy has caused serious environmental pollution problems. It is becoming increasingly urgent to find a green and clean new energy source. Microbial fuel cells (MFCs) have attracted much attention due to their renewable capabilities and green characteristics. MFCs still has certain limitations in its application process, such as its internal complexity, high cost of electrode separators and unstable power generation. Introducing different types of nanomaterials to build MFCs can solve these existing problems. However, how the introduced nanomaterials improve the electrochemical properties of MFCs remains to be further analyzed. To this end, this research will discuss the mechanism by which different regulatory strategies based on nanomaterials alter the electrochemical behavior of MFCs. Specifically, this research will focus on the impact of nanomaterials-based modification on the electrochemical performance of MFCs, including structural changes, material composite and new material preparations. The results show that the introduction of nanomaterials significantly improves the power density, current density and stability of MFCs, while enhancing catalytic activity, microbial adhesion and electron transfer efficiency. In this research, the analysis of changes in the electrochemical properties of MFCs by nanomaterials is conducive to the synthesis of novel electrochemically active nanomaterials and the development of high-performance MFCs.
