The rutile titania with hierarchical nanostructure was conveniently prepared in a room temperature ionic liquid (RTIL) of [Bmim]{sup +}Cl{sup -} system. The obtained materials were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N{sub 2} adsorption-desorption analysis. XRD patterns revealed that only rutile phase was formed in the ionic liquid of [Bmim]{sup +}Cl{sup -}. The SEM and TEM micrographs as well as N{sub 2} adsorption-desorption measurements showed that the nanorods of rutile titania were interaggregated to fabricate a large mesoporous structure and the voids packed in the nanorods formed a small mesostructure. It was proposed that the formation of rutile crystal phase was due to high acidity and high Cl{sup -} content in the special reaction media, and also the combination of ionic liquid-templated effects with so-called reaction limited aggregation resulted in the hierarchical nanostructure. - Graphical abstract: Ionic liquid of [Bmim]{sup +}Cl{sup -} was employed to prepare rutile titania with hierarchical nanostructure, in which the nanorods were interaggregated to fabricate a large mesoporous structure and the voids packed in the nanorods formed a small mesostructure.
