摘要：

in situ scanning tunneling microscopy (STM) and cyclic voltammetry show that a Ni monolayer can be deposited from a sulfamate solution on Au(111) at positive potentials with respect to the Nernst potential of the Ni/Ni2+ couple. This process is specific to H2NSO3- anions since ii could not be observed in the presence of sulfates. High resolution STM images suggest that the Ni layer builds up on the surface due to a complexation of Ni2+ by the sulfamate adlayer an the gold surface. (C) 1997 Elsevier Science B.V.
