摘要
The statistical thermodynamic theory of adsorbate-induced surface stress of anion adsorption monolayer on Au(111) has been established by using the lattice gas model and considering various components of the adsorbate-adsorbate interaction energies in the adlayer. The adsorbate-induced surface stress and its components due to various intermolecule forces of iodide adions on the Au(111) electrode surface have been calculated. The calculated surface stress of iodide adions on Au(111) approximates the experiment results. Among various components of the adsorbate-adsorbate interaction energies in the adlayer, the substrate -mediated interaction is significant for the adsorbate-induced surface stress, which shows that indirect contribution of the adsorption energy of iodide adions through the substrate-mediated interaction is very important.
