Closing the Loop in the Carbon Cycle: Enzymatic Reactions Housed in Metal-Organic Frameworks for CO Conversion to Methanol.

The preparation of value-added chemicals from carbon dioxide (CO) can act as a way of reducing the greenhouse gas from the atmosphere. Industrially significant C1 chemicals like methanol (CHOH), formic acid (HCOOH), and formaldehyde (HCHO) can be formed from CO. One sustainable way of achieving this is by connecting the reactions catalyzed by the enzymes formate dehydrogenase (FDH), formaldehyde dehydrogenase (FALDH), and alcohol dehydrogenase (ADH) into a single cascade reaction where CO is hydrogenated to CHOH.
