High performance of catalytic sheet filters of VO-WO/TiO for NO reduction.

Nitrogen oxide (NO) emissions in fuel from the stationary as well as from mobile sources primarily from power stations, industrial heaters, cogeneration plants, and diesel engines represent a major worldwide environmental problem. The selective catalytic reduction (SCR) of NO with NH over catalyst based on VO-WO/TiO (VWT) is the most effective benchmark technique to efficiently reduce NO emissions from stationary and mobile sources. Among the different transition metals (Mn, Nb, Co, Cr, Cu, Ce) used in current research work, the manganese could make up the loss of SCR activity caused by the decrease of VO loading (50%) in prepared VWT powder catalyst.
