The present invention relates to a catalyst for removing nitrogen oxides from an exhaust gas, a method for preparing the same and a method for removing nitrogen oxide in an exhaust gas using the same, and more particularly, to a catalyst for removing nitrogen oxides from the exhaust gas in which a ceramic fiber carrier is treated by hydrothermal reaction prior to washcoating to improve the hydrothermal stability of catalyst, a method for preparing the same and a method for 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 greatly enhanced.
