Abstract
Methods for catalytic generation of formic acid at an oxygen partial pressure of less than 1 bar and regeneration of the catalyst used in this process, wherein a polyoxometallate ion of the general formula [PMoxVyO40]n−, which serves as the catalyst, is brought in contact with an alpha-hydroxyaldehyde, an alpha-hydroxycarboxylic acid, a carbohydrate, a glycoside or a polymer containing a carbon chain with at least one OH group bound as a repeatedly occurring substituent to the carbon chain and/or an O, N or S atom occurring repeatedly in the carbon chain in a liquid solution in a vessel, at a temperature above 70 ° C. and below 120 ° C.
