土壤微生物燃料电池对有机物污染降解研究进展OA

Soil microbial fuel cells(SMFCs)are low-cost devices capable of converting chemical energy of organic matter into electricity through anodic microorganisms while simultaneously degrading organic pollutants in the soil.Therefore,they have promising applications in soil remediation and sustainable agriculture.However,the existing SMFCs still face limitations in terms of power generation and pollutant degradation efficiency.Moreover,many gaps are observed in their application for soil remediation of organic pollutants.Therefore,this article systematically reviews the research progress of SMFCs for degrading various organic pollutants in the soil,aiming to provide references for enhancing the power generation and degradation efficiency of SMFCs and guiding future research directions.First,the article elucidates the principles of SMFCs in degrading soil organic pollutants,analyzes the application of top-,insertion-,and U-type SMFCs,and deeply discusses the impacts of electrode materials and soil media on the SMFCs performance as well as the criteria for their selection.Second,it analyzes the different microbial species roles in the anode and their distribution changes in SMFCs.Accordingly,this article summarizes various methods to improve the power generation and degradation efficiency of SMFCs,such as optimizing electrode structures,adding electron mediators,and regulating environmental conditions.Future directions for developing SMFCs should focus on enhancing their stability and scalability,exploring highly efficient electrode materials and microbial strains,and expanding their applicability across different soil types and pollutants.
