One Dimensional LaTiO3-δ Nanorods for Solid Oxide Fuel Cells

Abstract

At present oxide materials in nano size provide new solutions and opportunities to guarantee better efficiency and stability for devices that produce or store sustainable energy. Due to their special shapes, compositions, chemical and physical properties, metal oxide nanomaterials are in the focus of current research efforts in all fields of science and technology. One-dimensional nanostructures, such as nanofibers, nanorods and nanotubes, have attracted significant attention due to the interesting confinement effects and the structure-related properties. One-dimensional nanostructures are attracting a great deal of attention due to their essential role in developing understanding of the fundamental concepts of quantum confinement effects. One-dimensional nanosized lanthanum titanate (LaTiO3−δ ) was synthesized using the hydrothermal technique to enhance the material’s electrical behavior. Using X-ray diffraction, scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (TEM), LaTiO3−δ was explored physicochemically. In SEM and TEM images, uniformly distributed nanorods were shown. Electrical properties analyzed using impedance spectroscopy revealed that the conductivity was in the order of 10−3–10−4 S/cm at a temperature range 500–630°C.
