Abstract To provide additional evidence on the synthesis path of methanol over Cu/ZrO2 catalysts, a three‐step in situ experiment was performed in a DRIFT cell. 13C‐labelled as well as common 12C paraformaldehyde and formic acid were adsorbed and subsequently hydrogenated under reaction conditions (0.5 MPa and 423 K). It was found that methanol was generated exclusively from the 2‐H2CO intermediate, not from adsorbed surface formate. Furthermore, the intermediacy of CO2- 3 in the reverse/water–gas shift reaction was shown.
