Abstract: Disclosed is a catalyst for producing an olefin including an oxygen carrier material and a dehydrogenation catalyst. The catalyst allows hydrogen to be converted into water by using oxygen inside the lattice of an oxide catalyst without the additional supply of oxygen, and thus, the conversion can be increased while the decrease in selectivity, which is a disadvantage of an additional oxidative dehydrogenation reaction (ODHP), is suppressed.
