| 英文摘要 | The selective catalytic reduction (scr) of nox with nh3 was studied over poorly-crystalline w-fe composite oxides (wafeox). the short-range order present within the w-o-fe structure was found to be responsible for the excellent scr activity, in which the strong atomic-level interaction between fe and w atoms promoted the formation of both lewis and bronsted acidity. the w-o-fe structure existed as amorphous overlayers, approximately 2 nm thick over the surface of crystalline particles after high-temperature aging as shown by high-angle annular dark field scanning transmission electron microscopy (laadf-stem). after treatment at 800 degrees c for 5 h, the wafeox catalysts still showed almost 100% no conversion in the range 300-450 degrees c with 100% n-2 selectivity, despite the loss in surface area. this resistance to the impacts of high temperature ageing guarantees high activity of scr catalysts which often suffer during high-temperature excursions as in the case of diesel exhaust due to diesel particulate filter (dpf) regeneration. |
