M. Nakamura et al., UNDERPOTENTIAL DEPOSITION OF ZINC IONS ON AU(111) IN PHOSPHATE SOLUTION (PH-4.6) - KINETIC AND STM STUDIES, Journal of electroanalytical chemistry [1992], 446(1-2), 1998, pp. 227-231
In phosphate solution at pH 4.6, in situ STM images on Au(111) were di
fferent in the potential regions where the Au(111) interface is taken
to be free from phosphate adsorption and where the upd Zn is formed. I
n the former region, the observed STM image was Au(111)(1 x 1), and in
the upd region, the image was taken to be (root 3 x root 3)R30 degree
s. As the phosphate is expected to adsorb on upd Zn by oxidative react
ion, it is suggested that the latter image is due to the adsorbed phos
phate species formed on upd Zn at Au(111) by upd induced adsorption. (
