Radiation induced synthesis of In2O3 nanoparticles - part 1: synthesis of In2O3 nanoparticles by sol-gel method using un-irradiated and γ-irradiated indium acetate

Abstract

Pure phase of In 2 O 3 nanoparticles were synthesized by sol-gel method in non-aqueous medium using un-irradiated and γ-irradiated indium acetate precursors. The as-prepared In 2 O 3 nanoparticles were characterized by XRD, FT-IR, SEM, TEM and TG techniques. The results showed that preirradiation to indium acetate with 10 2 KGy γ-ray absorbed dose has significant effects on the shape and size of the as-synthesized In 2 O 3 nanoparticles. In case of un-irradiated precursor, the SEM images show agglomerated and disordered spherical nanoparticles. In γ-irradiated case the particles showed coral-like structure. The as-synthesized In 2 O 3 nanoparticles prepared using γ-irradiated precursor showed higher thermal stability compared with those prepared using un-irradiated one. The results were discussed in view of the role of γ-irradiation on the morphology and thermal behavior of In 2 O 3 nanoparticles.

Morphological Characterization of Tungsten Trioxide Nanopowders Synthesized by Sol-Gel Modified Pechini's Method

“…Nowadays, nanopowders are produced by using different physical, mechanical, and chemical methods. Among the chemical processes, the sol-gel technique is known as a very simple and inexpensive approach in which shape and size of powder can successfully be controlled 7 . This technique uses three main routes for preparing metal oxides.…”

Controlling Self-Assembly of 3D In₂O₃ Nanostructures for Boosting Photocatalytic Hydrogen Production

“…In the FT-IR spectra (Fig. 1b), three obvious sharp band peaks at 420, 565, and 602 cm −1 are earmarked to the phonon vibrations of In-O bonds 30,36,40 . The evident photon modes at 131, 305, 366, 493, and 627 cm −1 were viewed in the Raman spectra (Fig.…”

Radiation Induced Synthesis of In2O3Nanoparticles - Part II: Synthesis of In2O3 Nanoparticles by Thermal Decomposition of Un-irradiated and γ-irradiated Indium Acetylacetonate

“…In our first submission, we stated with un-irradiated and γ-irradiated indium acetate with 10 2 kGy γ-ray absorbed dose as precursors for preparation of In 2 O 3 nanoparticles by sol-gel methods. The results demonstrated different morphologies and particle sizes for the as-synthesized In 2 O 3 nanoparticles as result of γ-irradiation 14 . In the present study, we will continue our investigation into using un-irradiated and γ-irradiated indium acetylacetonate (InAcAc) as precursors for preparation of In 2 O 3 nanoparticles in presence and absence of sodium dodecyl sulphate (SDS) surfactant by thermal decomposition process.…”
