摘要
The present invention relates to a catalyst for removal of nitrogen oxides from exhaust gas, a method of preparing the same and a method of removing nitrogen oxide in an exhaust gas using the same, and more particularly, to a catalyst for removal of nitrogen oxides from exhaust gas in which a ceramic fiber carrier is hydrothermal-treated prior to washcoating to improve the hydrothermal stability of catalyst, a method of preparing the same and a method of removing nitrogen oxide in an exhaust gas using the same.;The catalyst prepared according to the present invention has excellent hydrothermal stability and an activity of the catalyst remains for a long time. Further, by using this catalyst to remove nitrogen oxides in an exhaust gas, a removal ratio of the nitrogen oxides is improved more.
