摘要：

Anatase TiO2 single crystals with exposed {001} and {110} facets have been successfully synthesized using a modified hydrothermal technique in the presence of hydrogen peroxide and hydrofluoric acid solution; these single crystals exhibited enhanced photocatalytic activities for degradation of Methylene Blue dye under ultraviolet light irradiation.
