| چکیده | ||
| 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. | ||
