Unequivocal evidence of enantioselective, equilibrium separation of a racemic mixture on a naturally chiral metal surface is presented for the first time. The enantioselectivity is much higher than that of chiral molecules on mineral surfaces. Furthermore, the quantitative nature of the 13C labeling method provides the first direct measure of an enantiospecific adsorption energy difference on a chiral metal surface.
