摘要：
NiAgYO catalyst prepared using sol-gel method exhibited better catalytic behavior than NiAgO for the direct conversion of ethane to ethylene oxide (EO). An optimal EO yield of 7.6% with 19.8% selectivity was obtained at 290 degrees C. The catalysts were characterized by X-ray diffraction (XRD), H-2 temperature-programmed reduction (H-2-TPR), O-2 temperature-programmed desorption (O-2-TPD), and X-ray photoelectron spectroscopy (XPS). The results showed that the interaction between Y and Ag made the absorbed oxygen species hold proper electrophilic character, thereby improving the performance of the NiAgYO catalyst.
