生物阳极是微生物燃料电池（MFC）技术的决定性特征，并且常常限制其性能。在目前的工作中，我们报告了一种新型分层多孔结构作为高效生物阳极的工程，该结构由生物相容性壳聚糖和真空剥离石墨烯（CHI/VSG）组成。凭借分层孔隙和独特的 VSG，优化的生物阳极在无介体 MFC 中提供了 1530 mW m(-2) 的显着最大功率密度，比碳布阳极高 78 倍。
The bioanode is the defining feature of microbial fuel cell (MFC) technology and often limits its performance. In the current work, we report the engineering of a novel hierarchically porous architecture as an efficient bioanode, consisting of biocompatible chitosan and vacuum-stripped graphene (CHI/VSG). With the hierarchical pores and unique VSG, an optimized bioanode delivered a remarkable maximum power density of 1530 mW m(-2) in a mediator-less MFC, 78 times higher than a carbon cloth anode.
