Harnessing Natural Wood Architecture: A Self‐Supporting, Hierarchically Porous NiFe@Carbon Capacitive Anode Enhances Electricity Generation and Storage in Microbial Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study reports a mild “Zn(NO3)2 interlayer‐expansion” strategy combined with electrodeposition to produce a self‐supporting capacitive anode (NiFe@PC) that preserves the wood's native low‐tortuosity channels. The retained native architecture expands niches for microbial colonization.
