Sintesis Dan Karakterisasi Partikel Nanosperik Tio2 Melalui Metode Hidrotermal Gelombang Mikro

Abstract

Simple synthesis of nanospherical TiO 2 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.
