Hydrothermal synthesis and characterization of titanium dioxide nanotubes as novel lithium adsorbents
, Article Materials Research Bulletin ; Vol. 61, issue , January , 2014 , p. 70-75 ; Hajipour, H ; Askari, M ; Nusheh, M ; Sharif University of Technology
Abstract
The ion exchange process is a promising method for lithium extraction from brine and seawater having low concentrations of this element. To achieve this goal, it is vital to use an effective adsorbent with maximum lithium adsorption potential together with a stable structure during extraction and insertion of the ions. In this study, titanium dioxide and then lithium titanate spinel with nanotube morphology was synthesized via a simple two-step hydrothermal process. The produced Li4Ti5O12 spinel ternary oxide nanotube with about 70 nm diameter was then treated with dilute acidic solution in order to prepare an adsorbent suitable for lithium adsorption from local brine. Morphological and...
