1. A method of preparing a catalyst for oxidative dehydrogenation, comprising:
preparing a metal oxide AB2O4 powder as an active ingredient for oxidative dehydrogenation, wherein:
A is one or more metals selected from the group consisting of copper (Cu), radium (Ra), barium (Ba), strontium (Sr), calcium (Ca), beryllium (Be), zinc (Zn), magnesium (Mg), manganese (Mn), and cobalt (Co); and
B is iron (Fe);
pulverizing the metal oxide AB2O4 powder to produce a pulverized AB2O4 powder and classifying the pulverized AB2O4 so that the pulverized AB2O4 powder has a particle size of 0.1 to 75 μm;
preparing a catalyst slurry by dispersing the pulverized metal oxide AB2O4 powder in distilled water;
coating a porous support having an average pore size of 50 to 200 μm with the catalyst slurry; and
drying the catalyst slurry-coated porous support to obtain a catalyst for oxidative dehydrogenation,
wherein the obtained catalyst has a composition satisfying Equation 1 below:
X wt %+Y wt %=100 wt %,  [Equation 1]
wherein X represents a content of metal oxide AB2O4 and is 5 or more and less than 30, and Y represents a content of the porous support and is more than 70 and 95 or less.
