Abstract
The structures of monolayers of Hg atoms underpotentially deposited on Au(111) were resolved with the atomic force microscope. In sulfate, nitrate, and perchlorate electrolytes, a hexagonal overlayer with a 0.58±0.02-nm spacing was seen. In acetate, a hexagonal lattice exhibiting a 0.74±0.05-nm spacing was observed positive of the underpotential-deposition potential, a rhombic lattice with a 0.43±0.02-nm spacing was seen at intermediate potentials, and another hexagonal lattice with a 0.30±0.03-nm spacing was found just positive of bulk deposition.Keywords
