Motivated by the immerging applications of gold catalysts, we have been studying nanoscale restructuring of Au(111) surface upon interaction with electronegative molecules such as O, S and Cl. Surface restructuring with different ordering and incorporation of Au atoms into a growing surface compound phase have been observed and studied by scanning tunneling microscopy combined with temperature programmed desorption, X-ray photoelectron spectroscopy and low energy electron diffraction. Our studies provide new insight into the dynamic surface chemistry on Au.
