Facile fabrication of sodium titanate nanostructures using metatitanic acid (TiO 2.H 2O) and its adsorption property

Abstract

Fluffy sodium titanate nanostructures have been fabricated by a simple hydrothermal method with metatitanic acid as precursor. The obtained nanostructures exhibit as the aggregation of nanosheets, and the surface area of the nanostructure is about 110.59m 2/g. Such nanoarchitecture indicates high adsorption capacity to some metal ions, such as Cd 2+, and the maximum adsorption capacity has been estimated to be 255.18mg/g. The possible reasons that are responsible after its high adsorption ability, have been ascribed to the tiny structure, the ion-exchange ability and the large surface area of the sodium titanate nanostructures. And this may greatly enlarge its application potential as an adsorbent. © 2012 Gang Li et al.
