The anatase TiO_2 (001) surface has attracted extensive attention in surface science and for practical applications because of its excellent performance.However,the highly reactive (001) surface usually reconstructs to a (1 × 4)-(001) surface,which may potentially alter its properties.As a result,there are still controversial issues concerning the intrinsic performance of this surface.Recently,significant advances have been made in the surface science study of TiO_2 (001),which have elucidated its intrinsic physical and chemical properties.In this review,we summarize our present understanding of the structure and properties of the reconstructed TiO_2 (001) surface.First,we provide a brief background of the anatase TiO_2 surfaces,including its low-index surface structures and the synthesis of anatase TiO_2 nanocrystals with the (001) surface exposed.Next,we focus on the structure,formation mechanism,stability,and surface chemistry of the reconstructed TiO_2 (001) surface.Finally,we finish this review by highlighting the current challenges of this subject and providing future research perspectives.
