Enzymatic method for the conversion of carbon monoxide from industrial off-gases into formate

Nature Chemical Engineering volume 1, pages 338–339 (2024)Cite this article

Subjects

Decarbonizing the steel industry is crucial but challenging. Now, an enzymatic method is introduced for converting carbon monoxide from industrial off-gases into formate, offering a path towards carbon-neutral steel production. The enzymatic process achieves high selectivity, and operation of a 10-liter-scale reactor with real industrial emissions indicates its scalability and practical applicability.
