Metatranscriptomics Supports the Mechanism for Biocathode Electroautotrophy by “Candidatus Tenderia electrophaga”

mSystems, 2017
Biocathodes provide a stable electron source to drive reduction reactions in electrotrophic microbial electrochemical systems. Electroautotrophic biocathode communities may be more robust than monocultures in environmentally relevant settings, but some ...

Improved cathode materials for microbial electrosynthesis

Energy Environ. Sci., 2013
Microbial electrosynthesis is a promising strategy for the microbial conversion of carbon dioxide to transportation fuels and other organic commodities, but optimization of this process is required for commercialization. Cathodes which enhance electrode–microbe electron transfer might improve rates of product formation.

Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

ChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...

High‐Pressure Electrosynthesis of Succinic and Adipic Acids From CO2 and Ethylene in an Undivided Cell

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
The first sacrificial anodeless electrosynthesis of succinic and adipic acids from CO2 and ethylene is reported. Oxidation of DMF, oxalate, and urea at carbon‐based anodes facilitate the conversion in an undivided cell. Bayesian optimization of the reaction enables combined diacid current efficiencies up to 53%, surpassing previous works ...
