Abstract
The adsorption of phosphoric acid anions on the platinum (111) plane is investigated using Monte Carlo and density functional theory methods. The minimum energy structure is used to generate the adsorption configurations, indicating the preferred adsorption sites. The bond lengths was found from density functional theory calculations and used to gain further insight on the structure due to adsorption. From the density functional calculations the scanning tunnelling microscopy image of the specie with the lowest adsorption energy configuration and shortest bond length was produced.
