| Abstract: | The 5-parameter-Morse potential of interaction between hydrogen and palladium was constructed, the adsorption and diffusion of hydrogen atom on Pd(100),Pd(111),Pd(110) low index surfaces were studied by means of the classsical pair potential methods. The data of the adsorption sites, adsorption geometry, binding energy and eigenvibration etc were obtained for a hydrogen atom on Pd surfaces, they are in good agreement with the experimental results. Meanwhile, the construction of adsoption diffusion potential energy surface was systematically studied for three systems. |
