微生物燃料电池(MFC)是一种集废水处理与能量产生于一体的能源可持续发展技术,其利用微生物的催化作用将废水中的化学能转化为电能。MFC阴极催化性能直接决定了整个系统的产电水平,因此,阴极材料的制备与开发一直是研究热点。重点介绍了阴极基体材料和阴极催化剂的最新研究进展。其中,阴极基体材料包括碳基材料和非碳基材料,阴极催化剂包括贵金属、非贵金属、过渡态金属和导电聚合物催化剂等,并且比较了各种催化剂的物理性质、催化活性、氧化还原性能和对MFC系统产电能力的影响,为开发成本低、稳定性好、催化和氧化还原性能高的阴极材料提供了综合性参考。
Microbial fuel cell (MFC) is a technology that integrates wastewater treatment with energy generation and uses the catalytic action of microorganisms to convert the chemical energy in waste water into electricity. MFC cathode catalytic performance directly determines the level of the entire system of electricity production, therefore, the preparation and development of cathode materials has been a research hotspot. The recent progress in the research on cathode matrix materials and cathode catalysts is highlighted. Among them, the cathode base materials include carbon-based materials and non-carbon-based materials, cathode catalysts including noble metals, non-precious metals, transition metal and conductive polymer catalysts, etc., It can provide a comprehensive reference for the development of cathode materials with low cost, good stability and high catalytic and redox properties.
