Abstract:
... The commercial V₂O₅ −WO₃/TiO₂ (VWTi) catalysts often suffer from a serious joint deactivation by multiple heavy metals in the flue gas for NOₓ removal by NH₃-SCR. Herein, we report an extraordinary deactivation offset effect between Zn and As on VWTi with alleviation of the toxic effects of the heavy metals by “like cures like”. With the As&Zn content of 4 wt%, VWTi-As&Zn exhibited over 97% NO con ...
