In this way, the oxygen fugacity in the sample was in situ controlled independently of temperature and pressure. By using Cu-O system as an example, this technique was proved to be successful.展开更多

The dispersion, structure and morphology of the iron species on the Fe-Y catalysts were characterized by XRD, TEM and UV-Vis. The catalytic activities of Fe-Y samples were measured in selective catalytic redaction of NO with ammonia （NH3-SCR）. The results showed that the iron species on the HY zeolite support were mainly made up of isolated Fe3＋ ions, FexOy oligomers and a little amount of 〈 3 nm spherical Fe203 particles. Isolated Fe3＋ ions are predominating among all the Fe-Y catalysts. The sum of isolated Fe3＋ ions and FexOy oligomers took up more than 90% percent of total iron species on the Fe-Y till 10.0 wt% loading of Fe.展开更多
