Synthesis of anatase nanostructured TiO 2 particles at low temperature using ionic liquid for photocatalysis

Abstract

Anatase nanostructured TiO 2 particles were synthesized at low temperature by a modified sol–gel method using water immiscible room temperature ionic liquid as an effective template. Anatase phase was formed at low temperature (100 °C) by effective aggregation of TiO 2 particles with a self-assembled IL in the sol. The photocatalytic activity of the prepared sample was tested for the degradation of 4-chlorophenol. The TiO 2 particle prepared with ionic liquid showed higher photocatalytic activity than that prepared with the conventional sol–gel method under identical conditions.
