The interaction of NO with stoichiometric and defective TiO@sub2@ (110) surfaces has been studied by x-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), Auger electron spectroscopy (AES), electron energy loss spectroscopy (EELS) and low energy electron diffraction (LEED). Surfaces with different degree of defects have been characterized monitoring the evolution of the electronic surface structure, with the aim to study the influence of the surface defects on the interaction with NO. The interaction was studied for exposures up to 500L. However, the main effects occur already in the first 2L. The exposure of the surfaces to NO resulted in healing of defect sites without nitrogen adsorption.
