Development of ZnO/SiCh Nanocomposites Using Sol Gel Method

In this study, nanocomposite of ZnO-SKh was prepared by through in situ sol gel
method in which ZnOnanoparticles were dispersed in the silica glassy matrix. Zinc
Nitrate was added to Tetraethoxysilane at ratio molarity of Zinc
Nitrate:Tetraethoxysilane at 0.3:0.3 and 0.1:0.5. To promote the reaction, the Nitric
Acid and base, Sodium Hydroxide was added for the dried gel formation purpose.
The prepared dried gel of ZnO-Si02 at 120°C was heated to different calcination
temperatures which are at 400°C, 500°C, 600°C and 700°C. The structure and
thermal behavior of nanocomposite was identified through X-Ray Diffraction
(XRD), Fourier Transform Infrared Spectrometry (FTIR), Scanning Electron
Microscope (SEM) andThermo Gravimetric Analysis (TGA). Throughout this report
will be discussed more onthe structure andcharacteristic the synthesis nanoparticles
for its physical and chemical properties.
