Characterization and performance of V

Caiting LI, Qun LI, Pei LU, Huafei CUI, Guangming ZENG

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 156-161 doi: 10.1007/s11783-010-0295-x

Abstract: A series of CeO supported V O catalysts with various loadings were prepared with different calcinationThe effects of O and SO on catalytic activity were also studied.The experimental results showed that NO conversion changed significantly with the different V O loadingWith the V O loading increasing from 0 to 10 wt%, NO conversion increased significantly, but decreasedThe formation of CeVO on the surface of catalysts caused the decrease of redox ability.
