Oxidation of galena (PbS) is of crucial importance in environmental and geochemical processes. Hydrophobic nature of galena surface hinders the adsorption of water, which involves and determines the finally oxidative product of galena. In this work, DFT simulations of the adsorption of O2 and H2O on the hydrophobic galena surface have been performed. Results show that the isolated O2 molecule is dissociated...
