Abstract

V-doped TiO₂ quantum dots (QDs) possessing many Ti³⁺ defects were fabricated by simple hydrolysis using MCM-41 as a support. The QDs show high charge-separation efficiency and high photocatalytic activity due to the quantum size effect and the newly formed defect- and dopant-mediated band levels.
