Abstract:

Cr2O3 nanoparticles were prepared using Cr(NO3)3.9H2O as starting material, triethanolamine (TEA) as template and water as green solvent under microwave irradiation. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), photoluminescence (PL) and Raman spectroscopy. The size distribution of individual particles were determined to be about 25-70 nm. The catalytic activity of the prepared Cr2O3 nanoparticles was found to be more active than the bulk sample in the epoxidation of norbornene with 70% activity and 95% selectivity.

Microwave–Assisted Hydrothermal Synthesis and Optical Characterization of SnO2 Nanoparticles

Semiconductor nanoparticles exhibit size dependent properties due to quantum confinement effect that are not present in their bulk counterparts. In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analy...

Synthesis and Characterization of α-Fe2O3 Nanoparticles by Microwave Method

α-Fe2O3 (hematite) is the most stable iron oxide under ambient conditions. This transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. In this report, a novel microwave method for preparation of α-Fe2O3 nanoparticles has been developed. The process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...

Synthesis of ZnO Nanocrystals with Hexagonal (Wurtzite) Structure in Water Using Microwave Irradiation

Nanocrystals of ZnO were prepared by microwave irradiation using Zn (II) acetate and triethanol amin (TEA) as the starting materials and water as solvent. The nanocrystals of ZnO with hexagonal (Wurtzite) structure were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), UV-Vis absorption and FTIR Spectroscopy techniques.
