Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Beyond Technological Maturity: Understanding the Institutional Trajectories of Carbon‐Derived Renewable Methane in the European Energy System

EcoEnergy, EarlyView.
We demonstrate that the limitation of bioCO2‐derived methane is systemic rather than technological, and provide a validated framework for traceability, certification, and policy alignment enabling its integration into RFNBO‐compliant value chains and EU energy systems. ABSTRACT Renewable methane derived from biogenic CO2 (bioCO2) occupies a paradoxical

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.

Ammonium as a sustainable proton shuttle in bioelectrochemical systems [PDF]

, 2011
This work examines a pH control method using ammonium (NH4+) as a sustainable proton shuttle in a CEM-equipped BES. Current generation was sustained by adding NH3 or ammonium hydroxide (NH4OH) to the anolyte, controlling its pH at 7.
