The present invention relates to a catalyst for oxidative dehydrogenation reaction, a production method thereof, and a method for preparing butadiene using the same catalyst, and more specifically, to a catalyst for oxidative dehydrogenation reaction which reduces inactive crystalline structures and improves catalyst activity and stability by adding a specific amount of a specific ammonium hydroxide compound during the concentration and synthesis of the catalyst for the oxidative dehydrogenation reaction, and provides an effect of ultimately improving the conversion of butene and the selectivity of butadiene in the production of butadiene; a production method of the catalyst; and a method for preparing butadiene using the same catalyst. 본 발명은 산화적 탈수소화 반응용 촉매, 이의 제조방법 및 이를 이용한 부타다엔의 제조방법에 관한 것으로, 보다 상세하게는 산화적 탈수소화 반응용 촉매의 농축 합성 시, 특정 암모늄 하이드록사이드계 화합물을 특정 함량 첨가하여 비활성인 결정구조를 감소시켜 촉매 활성 및 안정성을 향상시키고, 궁극적으로는 부타디엔 제조 시 부텐의 전환율 및 부타디엔의 선택도 등을 향상시키는 효과를 제공하는 산화적 탈수소화 반응용 촉매, 이의 제조방법 및 이를 이용한 부타다엔의 제조방법에 관한 것이다.
