Interaction of HCOOH and H2CO with K3PMo12O40 has been studied by IR spectroscopy. HCOOH adsorbed mainly in molecular form due to hydrogen bonds with surface oxygen ions. Two forms of adsorbed H2CO were observed depending on the pressure. At low pressures it adsorbed on Brönsted acid sites with the formation of hydrogen-bonded complexes. Dioxymethylene groups and a small amount of polyoxymethylene groups were formed at higher pressures. In contrast to oxide catalysts, formates were formed only in small amounts in the absence of oxygen. This can be explained by the formation of new surface adsorption sites Mo ions-due to a partial reduction of K3PMo12O40 during its interaction with HCOOH and H2CO.
