Abstract The reaction of formic acid with pre-oxidised Cu(110) surfaces is re-evaluated on the basis of new temperature programmed desorption and X-ray photoelectron spectroscopy results. It is shown that at high oxygen coverages and for high formic acid exposures, or after co-adsorption of formic acid and dioxygen, a surface carbonate is formed. The carbonate appears to be very similar to that formed by the oxidation of CO 2 , at higher pressures, which was reported in an earlier paper. The results also account for a number of unexplained observations on this system and provide further support for the involvement of carbonate in methanol synthesis on copper.
