SYNTHESIS AND CHARACTERIZATION OF SILVER - ALUMINA NANOCOMPOSITES

Abstract

The work comprised in this thesis entitled "Synthesis and characterization of silver-alumina nanocomposites" consists of five Chapters, Introduction, Experimental details, Results and discussion, Summary and Future prospects are the Chapters 1, 2, 3, 4 and 5, respectively. A simple thermal decomposition approach has been used for the synthesis of silver-alumina nanocomposites. Two different supports, i.e. sol-gel alumina and commercial alumina (with/ without calcination) ' were used for the preparation of silver-alumina nanocomposites. The nanocomposites were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, thermal gravimetric analysis, surface area measurements, field emission scanning electron microscopy coupled with energy dispersive- X-ray analysis, transmission electron microscopy and diffuse reflectance spectroscopy
