DFT study on TiO2 facet-dependent As(III) oxidation process: Importance of As(IV) species
Surface Science(2023)
Abstract
•As(IV) formation step determined the reactivity of As(III) oxidation.•As(III) oxidation on TiO2 surfaces represents facet-dependent reactivity.•Theoretical overpotential linearly correlated to the adsorption energy of As(IV).•Electronic structure of the adsorbed As(III/IV) dominated the reactivity.
