 Abstract
In this paper the selective reduction catalyst (SCR) for controlling the NOx at high temperature range was studied. XRD and FT-IR BET analysis was also performed to determine the structural properties and adsorption/desorption characteristics of the catalyst. In the case of anatase support, a negligible NOx conversion was observed, but the catalyst made using W as a active metal showed an excellent ability to remove NOx. In particular, the exhibited a rapid increase in the catalytic activity due to the presence of W for the NOx conversion compared to that of using the pure at a high temperature range over . In addition, the phenomenon of reduced reaction activity due to the heat shock for a long time was found to be suppressed.
