The reaction between hydrogen and oxygen on Pt(111) is investigated with molecular beam relaxation spectroscopy in the temperature range between 300 and 1200 K. Three procedures were used for preparing the surface, resulting in different reactivities

Adsorption of hydrogen on oxygen covered Pt(111) is investigated in the temperature range 300–600 K by titration of adsorbed atomic oxygen with hydrogen from a supersonic beam. In most experiments the conditions were such that hydrogen adsorption w

The morphology of a Cu(110) surface after low coverage Pt atom deposition from the vapour phase is studied with thermal energy atom scattering (TEAS) in the temperature range of 200–800 K. Both cross section measurements and diffraction analysis re

The interaction of H2O with rutile TiO2(110) surfaces with different defect densities (oxygen vacancies) was studied with TPD, work function measurements and XPS. On the nearly perfect surface, a thermal desorption peak is observed at 250–300 K whi

Bismuth postdosing thermal desorption mass spectroscopy (BPTDS) is a new surface analytical technique which uses vapor-deposited Bi atoms to suppress bond-breaking reactions in adsorbed molecules, so that they desorb intact for mass spectral identifi

The interactions of cyclohexene with a Pt(111) surface have been studied using a combination of bismuth postdosing thermal desorption mass spectroscopy (BPTDS) and high-resolution electron energy loss spectroscopy (HREELS). BPTDS is a technique which

The interactions of 1,3- and 1,4-cyclohexadiene with Pt(111) have been studied with bismuth postdosing thermal desorption mass spectroscopy (BPTDS) and high-resolution electron energy loss spectroscopy (HREELS). Both species adsorb molecularly on Pt(

The applications of bismuth postdosing thermal desorption mass spectroscopy (BPTDS) to the analysis of molecular and nonmolecular adsorbates on Pt(111) is briefly reviewed. In this method, about one monolayer of bismuth adatoms is vapor deposited ont

A short review of the hydrogen-oxygen reaction on Pt(111) is given in which the emphasis is put on the apparent contradictions between experiments reported in the literature. We consider these results in the light of our recent observation that certa

The influence of the order of an oxygen adlayer on Pt(111) on the adsorption of D 2 has been investigated using a combination of He diffraction and reactive scattering techniques. A close correlation was found between the onset of the order/disorder
