| 英文摘要 | The titanium-bearing blast furnace slag (BFS), a solid waste with high TiO2 content (around 20%) and huge production (3.6 million tons per year), has caused serious environmental problems in China. The reuse of BFS in making DeNO(x) catalysts has been confirmed to be promising because of its low cost and high effectiveness for DeNO(x). In this work, four V2O5-WO3/TiO2-SiO2 samples from BFS and commercial Ti/Si were made with different amounts of Al2O3/Fe2O3/SO42- dopants to reveal the unique structure effect of a slag-based catalyst on the catalytic behavior for DeNO(x). Catalyst characterization clarified that the Al2O3/Fe2O3/SO42- dopants from BFS may facilitate the formation of Ti-O-Si linkages with abundant structure defects. The structure possibly played a key role in acquiring a high surface area, well-dispersed active VOx species, sufficient weak acid sites and a high amount of O-ads and V4+ species for the slag-based catalyst. These advantages in structure were confirmed by catalytic tests showing superior DeNO(x) performances. Nonetheless, too many SO42- dopants caused agglomeration of TiO2-SiO2 particles, formation of strong acid sites and a high amount of O-ads species to negatively impact the DeNO(x) activity, selectivity and catalyst lifetime. |
