Adsorption of SF₆ Decomposed Products over ZnO(1010): Effects of O and Zn Vacancies.

ABSTRACT: We carried out a density functional theory study to investigate the adsorption behavior of four kinds of SF₆ decomposed products over the ZnO(101̅0) surface. The effects of O and Zn vacancies on the surface were also considered. For perfect ZnO(101̅0) surface, the adsorption of SO₂ and H₂S exhibits stronger chemical interactions compared to the adsorption of SOF₂ and SO₂F₂. For SO₂ and H₂S adsorption, there may exist new chemical bond formation between the molecule and the surface and the H₂S molecule experiences one H-S broken bond. The introduction of O vacancy cannot obviously enhance the chemical interactions between these four molecules and the surface. However, the Zn vacancy on the sur
