Structure determination of formic acid reaction products on TiO2(110)

Article Abstract:

The local structure of the surface species produced on the rutile TiO2(110) surface is determined as a result of room temperature exposure to formic acid using chemical-state specific scanned-mode photoelectron diffraction from O 1s and C 1s photoemission. The results exclude the possibility of a large (1/3) fractional occupation by the formate species of a second site azimuthally rotated by 90 degree and bonded to a surface oxygen vacancy site.

Local structure of CO coadsorbed with O on Ni(111): a temperature-dependant study

Article Abstract:

The local geometry of the CO absorbed onto a Ni(111)(2*2)-O surface is investigated using C 1 s scanned-energy mode photoelectron diffraction (PhD). The results confirm the quantitative site occupations deduced which is C 1 s and O 1 s photoelectron binding energy shifts to fingerprint the local site changes.

Structure changes of the W(211) surfaceinduces by ultrathin films of Rh, Pt, and Pd(super +)

Article Abstract:

Rh, Pt, and Pd are formed to cause a reconstruction of the W(211) surface similar to oxygen. When covered with a thin film of Pt, Pd or Rh on W(211) surface, an nx1 type of superstructure is formed upon annealing.
