Abstract

Abstract : The surface protonation/deprotonation can change the photocatalytic redox preferences of TiO2 {001} and {101} surfaces. Abstract : It is widely believed that anatase TiO2 {001} and {101} surfaces acts as the oxidative and reductive sites in photocatalytic reactions, respectively, which is attributed to their different intrinsic surface structures. However, we demonstrate that the photocatalytic redox preferences of TiO2 {001} and {101} surfaces are determined by the adsorbate-reconstructed surface structure instead of their intrinsic surface structures, which can be modulated by surface protonation/deprotonation.
