摘要：
The adsorption of molecular sulfur on TiO2(110)(1 x 1) has been studied with scanning tunneling microscopy and photoelectron spectroscopy. At room temperature S binds dissociatively to 5-fold coordinated Ti atoms and oxygen vacancies. At elevated temperatures (120-440 degreesC) sulfur replaces surface oxygen atoms. Evidence was found that the reduction state of TiO2 crystals strongly affects the surface coverage of S at elevated temperatures. The rate of the O-S site exchange is kinetically limited by the arrival of diffusing bulk defects at the surface. (C) 2001 Elsevier Science B.V. All rights reserved.
