abstract = {Pore structure plays critical roles in electrode kinetics but very challenging to tailor porous nanowires with rationally distributed pore sizes in a bioelectrochemical system. Herein a hierarchically porous nanowires-material is delicately tuned for an optimal pore structure by adjusting the weight percentage of SiO2-hard template in an electrospinning precursor solution. The as-prepared 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, respectively. The 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 centers. This work provides thoughtful insights to design of hierarchical porous electrode for high-performance MFCs and other bioelectrochemical system devices.}
