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.

The effect of intermittent anode potential regimes on the morphology and extracellular matrix composition of electro-active bacteria

Biofilm, 2022
Electro-active bacteria (EAB) can form biofilms on an anode (so-called bioanodes), and use the electrode as electron acceptor for oxidation of organics in wastewater. So far, bioanodes have mainly been investigated under a continuous anode potential, but

Polypyrrole‐Coated Hierarchical 3D Printed Graphene Electrodes for Reusable High‐Performance Biophotovoltaic System

EcoMat, Volume 8, Issue 9, September 2026.
A 3D‐printed polypyrrole/reduced graphene oxide (PPy/rGO) lattice anode with high porosity enhances biophotovoltaic (BPV) power density and current density by coordinating biofilm adhesion, light penetration, and endogenous mediator diffusion. Optimized PPy electropolymerization maximizes photocurrent and cell–electrode affinity.
