Nanomaterials for facilitating the microbial extracellular electron transfer (EET) process have drawn increasing attention due to their specific physical, chemical and electrical properties. This review summarizes the research advances of nanomaterials for accelerating the EET process. Nanostructured materials, including oligomer, carbon nanotube (CNT), graphene, metal, metal oxides, and polymer, exhibit numerous admirable properties such as large surface area, high electrical conductivity, and excellent catalytic activity. In this review, depending on the exact site where the nanomaterials work, the nanomaterials are classified into four groups: inside-membrane, interface, inside-biofilm and interspecies. Synthesis of the nanomaterials, EET enhancement performance, and corresponding enhancement mechanisms are also discussed. In spite of the challenges, nanomaterials will be extremely promising for promoting the EET process application in the future.
由于具有特殊的物理、化学和电气特性，用于促进微生物细胞外电子转移 (EET) 过程的纳米材料引起了越来越多的关注。本文综述了用于加速 EET 过程的纳米材料的研究进展。纳米结构材料，包括低聚物、碳纳米管 (CNT)、石墨烯、金属、金属氧化物和聚合物，具有大表面积、高导电性和优异的催化活性等许多令人钦佩的特性。在本综述中，根据纳米材料的确切工作位置，将纳米材料分为四类：内膜内、界面、生物膜内和种间。还讨论了纳米材料的合成、EET 增强性能及其相应的增强机制。尽管存在挑战，但纳米材料在未来促进 EET 过程的应用将具有广阔的前景。
