Abstract
The synthesis of TiO2 nanorods with anatase structure has been achieved from the necking of truncated nanoparticles by oriented attachment using
titanium ethylenediaminetetraacetic acid (EDTA) chelated complex as a molecular precursor. The preparation was carried out
under mild conditions using a simple solvothermal process. The influence of EDTA over the growth of nanocrystallites and the
various other factors which contribute to the development of 1D TiO2 nanostructure are investigated. At a relatively lower temperature, titania nanopowders are obtained, and the anatase phase
crystallization is verified by wide angle X-ray diffraction. The evolution of rod-shaped TiO2 with tapered edges has been confirmed by transmission electron micrographs. The well aligned lattice fringes of TiO2 nanorod towards [001] direction is investigated by HRTEM. The SEM images show the surface configuration of overall aggregates
of titania crystallites consisted of primary particles which are densely packed in an orderly texture. The moderate shift
in the absorption band towards higher energy region of the absorption spectrum confirms the weak carrier confinement effect
in the sample.
