Biochar Cathodes for Bioelectrochemical Systems: Understanding the Effect of Material Heterogeneity on Performance for Abiotic Hydrogen Evolution Reaction

ChemElectroChem, Volume 12, Issue 20, October 16, 2025.
This study investigates industrial‐scale granular biochar (GB) as cathode material to produce in situ abiotic H2, which could be utilized within CO2‐reducing bioelectrochemical systems to produce value‐added products. GB from beechwood pyrolyzed at 740 °C shows lowest hydrogen evolution reaction (HER) overpotential; however, heterogeneous ...
