Abstract
Abstract
Simple synthesis of nanospherical TiO2 by microwave hydrothermal method has been investigated. Titanium tetra isopropoxide (TTIP) and tetra methyl ammonium hydroxide (TMAOH) were used as precursor. The crystal phase and microstructure were characterized by X-Ray Diffraction (XRD) and transmission electron microscopy (TEM) including selected area diffraction (SAED). The presence of intense peak in the XRD patterns confirmed to anatase and in good agreement with SAED patterns. Nanospherical of particles were clearly seen in the TEM image and the size of particles was approximately 4-5 nm.
