A hydrothermal synthesis of tio2 nanostructure and study of its structural, morphology and calculate crystalline size using Debye-scherer equation

Abstract

Samples of TiO2 nanoparticles were hydrothermally synthesized and characterizing its structural, optical properties and study its morphology. The crystalline structure and grain sizes were studied by X- Ray Diffractometer, while diameters and shapes of crystalline grains were characterized by Field Emission Scanning Electron Microscope (FESEM). FESEM images has a clear measure of synthesized nanostructure dimensions where the diameter of grains about (117.1 ~ 148.3 nm) which having a spherical grains shape. By XRD characterization lattice spacing (dhkl) were measured to be about 1.24 - 3. 24 Aº, and have some peaks in special directions h k l = (110), (020), (120), (121), (220) (112). The mean crystalline size D (nm) is calculated by Debye Scherer equation and it has range 30~200 nm3.
