Synthesis and Reactivity in Inorganic, Metal-Organic,and Nano-Metal Chemistry

Abstract

Synthesis of In2O3 nanoparticles by thermal decomposition of γ -irradiated indium acetate in presence of benzyl alcohol has been studied. The interaction between indium acetate and benzyl alcohol led to formation of a white gel. Thermal decomposition of the gel gave In2O3 nanoparticles. The results showed that the indium complex decomposes to In2O3 via an intermediate compound. The characterization of the intermediate as well as final compound was carried out by thermogravimetry, Fourier-transform infrared (FT-IR) spectroscopy, x-ray diffraction, and scanning electron microscopy. Nanoparticles of cubic In2O3 with crystallite size in the nanoparticles range were formed after calcinations at temperature up to 900◦C.
