英文摘要 | An investigation has been made on the adsorption and decomposition of formic acid on slightly oxidized Nb(110) surface (O/Nb atom ratio = 0.2) using high resolution electron energy loss spectroscopy (HREELS), and a corresponding surface reaction mode is given. At 140 K, formic acid of low exposure on such an Nb(110) surface decomposed to formate, which bonded on Nb in monodentate configuration, simultaneously some formate decomposed to CO, which adsorbed on the surface. Formic acid multilayers formed when the exposure was high. While the temperature was increased to above 190 K, multilayer formic acid desorbed, and the surface was covered with monodentate-bonded formate and CO. In the temperature range of 250-300 K, chemisorbed formate changed from monodentate configuration into bridging configuration and CO molecules disappeared. The decomposition of formate at higher temperatures led to the oxidation of Nb. The formate formed in the high exposure case was so stable that it did not decompose even the temperature was as high as 540 K. |
