PROBLEM TO BE SOLVED: To provide a dehydrogenation catalyst applicable to the production of alkenes by dehydrogenating alkanes which stably indicates high catalytic activity and high selectivity. SOLUTION: A catalyst is prepared by a method in which platinum, iridium, and tin are supported on a composite carrier in which zinc oxide is supported on γ-alumina carrier at least 150 m2/g in surface area, at least 0.55 cm3/g in pore volume, and 90-200 angstrom in average pore diameter in which the volume of pores 90-200 angstrom in pore diameter occupies at least 60% of the total pore volume. |
