Recently, it has been observed, that ceria may be used as a hydrogenation catalyst for the selective hydrogenation of triple bonded unsaturated hydrocarbon towards double bonded unsaturated hydrocarbons.1 In light of these observations we have started a systematic study of a CeO2(111) single crystal surface of a film representing bulk ceria in various states of reduction to investigate its interaction with hydrogen using a number of surface and bulk&lt;!--[endif]----&gt;2,3 sensitive experimental techniques, including IRAS, HREELS, TPD and STM as well as resonant nuclear reaction analysis (rNRA) and theoretical calculations.4&lt;!--![endif]----&gt; &lt;!--[endif]----&gt;It is shown that adsorption and absorption happens and both are related to the state of reduction. Details will be discussed in the presentation.
