Abstract
In molecule-surface systems, converged PSP calculations and all-electron calculations were shown to yield very similar results. Through examinations, it was found that DFT energy errors were not limited to CO adsorption on (111) metal surfaces, but occur for many reactions involving CO. In addition, it was also shown that the underestimation of CO bond energy loss in migration from the top to the hollow site was largely responsible for the incorrect site preference obtained by DFT-GGA calculations.
