{l_brace}0 1 0{r_brace}-faceted anatase TiO{sub 2} nanocuboids have been fabricated by hydrothermal route using peroxotitanium complex solution as precursor. The effects of reaction time, the amount of urea and temperature on the formation of {l_brace}0 1 0{r_brace}-faceted anatase TiO{sub 2} were characterized by XRD, FESEM and TEM. The growth mechanism of nanocuboids was proposed that the nanocuboids were formed by the transition from H{sub 2}Ti{sub 2}O{sub 5}{center_dot}H{sub 2}O phase to anatase TiO{sub 2} in the basic condition. The photocatalytic performance of the prepared samples was tested in the degradation of Rhodamine B and the anatase nanocuboids exhibited enhanced photocatalytic activity compared with the standard P25 powders. - Graphical abstract: Anatase TiO{sub 2} nanocuboids with exposed {l_brace}0 1 0{r_brace} facets prepared by a hydrothermal method exhibit superior photocatalytic activity for degradation Rhodamine B to P25. Highlights: Black-Right-Pointing-Pointer One-step route to prepare {l_brace}0 1 0{r_brace}-faceted anatase TiO{sub 2} nanocrystal is developed. Black-Right-Pointing-Pointer Control synthesis of {l_brace}0 1 0{r_brace}-faceted anatase nanocuboids. Black-Right-Pointing-Pointer Mechanism on formation of anatase nanocuboids under hydrothermal condition. Black-Right-Pointing-Pointer The enhanced photocatalytic reactivity of nanocuboids is attributed to reactive facets.
