Abstract
Formaldehyde is obtained from CO2 through hydrogenation of CO2 to methanol while the subsequent oxidation of methanol yields formaldehyde. This formaldehyde combined with the electrochemically produced glycolaldehyde generates sugars, thus establishing a route from CO2 to sugars.
Claims20
A method making a sugar, comprising the steps of electrochemical reduction of CO2 to form glycoaldehyde, wherein the glycolaldehyde then operates as an autocatalyst to promote conversion of formaldehyde to the sugar in a formose reaction.
