摘要
Graphene oxide （GO） can be reduced to graphene in a normal aerobic setup under ambient conditions as mediated by microbial respiration of Shewanella cells. The microbially-reduced graphene （MRG） exhibited excellent electrochemical properties. Extracellular electron transfer pathways at the cell/GO interface were systematically investigated, suggesting both direct electron transfer and electron mediators are involved in the GO reduction.
Graphene 氧化物(去) 能在由 Shewanella 房间的微生物引起的呼吸调停了的周围的条件下面在正常氧气的安装被归结为 graphene。减少 microbially 的 graphene (MRG ) 展出了优秀电气化学的性质。在 cell/GO 接口的细胞外的电子转移小径系统地被调查，建议两个直接电子转移和电子调停人涉及 GO 减小。
