| Abstract | In this paper, the nanosized Cr2O3 were prepared by Sol-Gel method coupling with azeotropic distillation method. The obtained nano-powders were characterized by BET, XRD, TEM, Fr-IR, XPS and H-2-TPR techniques. Fr-IR patterns revealed that the infrared absorption peaks of Cr-O bond in Cr2O3 nano-powders blue shift and the intensity of the absorption of Cr-O bond (651.8cm(-1)) increases. The mechanism of red shift and blue shift in nano-powders of oxides was discussed, and it was concluded that the crystal structure of nano-powders of oxides influences their infrared spectra. The catalytic performance of nano-Cr2O3 catalyst for oxidative dehydrogenation of ethane with CO2 was compared with that of normal Cr2O3 catalyst. The nano-Cr2O3 catalyst exhibits much higher ethane conversion and higher ethylene yield than those of normal Cr2O3 catalyst. At 973K, nano-Cr2O3 catalyst shows 77.1% ethane conversion and 58.98% ethylene yield for the oxidative dehydrogenation of ethane with carbon dioxide to ethylene. |
