Role of microbial electrosynthesis system in CO capture and conversion: a recent advancement toward cathode development.

Microbial electrosynthesis (MES) is an emerging electrochemical technology currently being researched as a CO sequestration method to address climate change. MES can convert CO from pollution or waste materials into various carbon compounds with low energy requirements using electrogenic microbes as biocatalysts. However, the critical component in this technology, the cathode, still needs to perform more effectively than other conventional CO reduction methods because of poor selectivity, complex metabolism pathways of microbes, and high material cost.
