Kazempoor, G. Pirug] The coadsorption of formic acid and water on Au(111) surfaces has been investigated by means of vibrational and photoelectron spectroscopy (HREELS, XPS). Formic acid adsorbs at 90K molecularly with vibrational modes characteristic for flat lying zig-zag chains in the mono- and multilayer regime, like in solid formic acid. Annealing results in a complete desorption at 190K. Sequential adsorption of formic acid and water at 90K shows no significant chemical interaction. Upon annealing the coadsorbed layer to 140K a hydrogen-bonded cyclic complex of formic acid with one water molecule could be identified using isotopically labelled adsorbates (D2O, H13COOD). Upon further annealing this complex decomposes leaving molecularly adsorbed formic acid on the surface at 160K, accompanied by a proton exchange between formic acid and water.
