摘要：

Water dissociation on 0(n x l)-Ag(110) phases has been studied as a function of oxygen coverage and surface temperature by He scattering at thermal energy and photoemission spectroscopy. A new phase of OH with (I X 1) periodicity with respect to the Ag(110) substrate has been observed following H2O adsorption at T(s) = 130 K on the 0(2 x 1) phase and annealing at T(s) = 210 K. OH groups arrange in chains along the [110BAR] direction. Hydroxyl groups strongly interact along the chain as shown by the dispersion of electronic states along [110BAR].
