Abstract

H₂ adsorption on Fe(OH)₃ is investigated by using the density functional theory (DFT) for the H₂ molecular orientation θ= 10° with respect to the surface normal and that for the H ₂ molecular orientation θ = 70°. From the PES results of H₂-Fe(OH)₃ system, we find that for the H₂ molecular orientation θ= 10°, a potential well is at Z = 4.2 Å with a depth of around 4.4 meV while for the H₂ molecular orientation θ = 70°, a potential well is at Z = 3.0 Å with a depth of around 17.7 meV. The small binding energy and the positions of potential well with respect to the surface of these adsorption states are typical for physisorption.
