Abstract

We report Monte Carlo simulations of a new lattice-gas model for electrochemical adsorption of urea on single-crystal Pt(100) electrodes. The simulation results agree well with those of our experiments. These include an ordered c(2×4) adsorbed urea phase and sharply peaked voltammograms which we interpret as associated with a phase transition between the c(2×4) phase for potentials on the positive side of the peak and a fully hydrogen covered (l×l) phase on the negative side.
