Adsorption and reaction of CO2 and CO2/O CO-adsorption on Ni(110): Angle resolved photoemission (ARUPS) and electron energy loss (HREELS) studies

Carbon deposition on borated alumina supported nano-sized Ni catalysts for dry reforming of CH4

“…7), while adsorbed CO 2 (2328 cm À1 ) and CO (2144 cm À1 ) bands were clearly observed on all the four catalysts, indicating that the reaction proceeds via 2a pathway, i.e. the activation and dissociation of CO 2 on Ni sites [43,44], as proposed in steps (10) …”

Carbonate formation on the O-enriched RuO2(110) surface

“…5-10 and oxygen-precovered metal surfaces, e.g., Refs. [11][12][13][14][15]. Less adsorption studies have been performed on well-defined oxide surfaces, 3,16,17 as the limited electric conductivity of many oxides hinders the use of electron spectroscopic methods.…”

Photoemission Study of CO2adsorbed on K/Cu(110). Analysis of Adsorbate Induced Structures

“…It is known that within a CO2 pressure range of 10 -6 -10 -4 Pa, CO2 interacts with ion pumps as well as hot filaments loading to formation of CO and its preferential adsorption on the sample (e.g. [1]). The gas adsorption experiments were performed with extreme care; the dosing system was flushed repeatedly with CO2 and the ion pump was closed during admission of CO2.…”

“…Adsorption and reaction of CO2 on alkali modifed (or not) various metal surfaces were studied by photoelectron spectroscopy, thermally programmed desorption (TPD) and changes in work function (ΔΦ) [1][2][3][4][5][6][7][8][9][10][11][12]. It was shown that the adsorption of CO2 and the attendent processes are substrate and face specified.…”

“…However, the photoemission spectroscopy can provide information on the identity and bonding of an adsorbed species and fully characterize the interface. Closely related to the solid CO2, the often used model [1] of the relative orientation of the linear CO2 molecules within a two-dimensional layer is postulated. For this model of a T-shaped arrangement, with the distance between C and nearest O atom of a second molecule of 0.296 nm [8], the number of molecules that complete the hypothetical monolayer on Cu(110) is equal to the density in the "solid CO2" layer, i.e.…”
