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.
