摘要: Abstract The effects of Mn and Fe doping into the CeO 2 (111) surface on simultaneous removal Hg H S was investigated, a density functional theory calculation with on-site Coulomb interaction taken account adopted. adsorptions Hg-containing species perfect (111), Mn/CeO Fe/CeO surfaces were studied, results showed that dopants facilitated adsorption, more charge transferred from atom to metal doped surfaces; HgS preferred adsorb dissociated mode, while molecular mode surfaces. reaction mechanism show by can easily react leading formation surfaces, which is crucial capture mercury.
