Density functional theory calculations corrected by on-site Coulomb interaction have been conducted to illuminate the effect of O vacancies on the surface reactivities toward direct CO oxidation at CeO 2 (110) and (111). CO adsorption at and further reaction with various surface O at the vacancy were systematically calculated, and extensive geometric and electronic analyses were also performed...
The adsorption of sodium 4-ethyl naphthalene-1-sulfonate has been studied by cyclic voltammetry and in situ scanning tunneling microscopy (STM). Electrochemical STM imaging reveals an ordered adlayer with a (4x4) structure on Cu(111) in 0.1 M HClO 4 in which the surfactant molecules are oriented parallel to the surface. The structural details of each molecule are well discerned. A structural...
