主 题：hierarchically porous nanowires microbial fuel cells interfacial electron transfer biofilm
摘 要：Pore structure plays critical roles in electrode kinetics but very challenging to tailor porous nanowires with rationally distributed pore sizes in a bioelectrochemical *** a hierarchically porous nanowires-material is delicately tuned for an optimal pore structure by adjusting the weight percentage of SiO_(2)-hard template in an electrospinning precursor *** asprepared optimal electrospinning nanowires further used as an anode of microbial fuel cells(MFCs),delivering a maximum output power density of 1,407.42 mW·m^(−2)with 4.24 and 10 times higher than that of the non-porous fiber and carbon cloth anode,*** great enhancement is attributed to the rational pore structure which offers the largest surface area while the rich-mesopores well match with the size of electron mediators for a high density of catalytic *** work provides thoughtful insights to design of hierarchical porous electrode for high-performance MFCs and other bioelectrochemical system devices.
