ABSTRACT
Titanium dioxide (TiO2) crystals are the most widely investigated photocatalysts. The performance of TiO2 photocatalysts is sensitively affected by their surface atomic structures and surface electronic structures. Controlling the shapes of TiO2 is becoming an important and popular strategy to tune the surface atomic structures and electronic structures so that an optimal performance can be reached. The chapter presents the, latest development in controllable synthesis of anatase TiO2 with well-deϐined facets and their unusual photocatalytic properties.
