The results of the NO adsorption on the TiO2(110) surface indicate the intensity exchange of the desorption gas. The clusters of the NO adsorption on the TiO2(110) were calculated with the molecular orbital theory of MOPAC and Gaussian, and the charge distribution and energy level of the TiO2(110) clusters were investigated. The stable NO adsorption on TiO2 surface was suggested.

Key words: nitrogen oxide, titanium dioxide, adsorption, desorption, molecular orbital theory
