Synthesis of titanate nanostructures using amorphous precursor material and their adsorption/photocatalytic properties

, 2012
This paper reports on a new and swift hydrothermal chemical route to prepare titanate nanostructures (TNS) avoiding the use of crystalline TiO2 as starting material. The synthesis approach uses a commercial solution of TiCl3 as titanium source to prepare
