(57) [Problem] To provide a dehydrogenation catalyst used for production of an alkene by dehydrogenation of an alkane, wherein carbon deposition on the catalyst is suppressed. SOLUTION: The surface area is 150 m 2 / g or more and the pore volume is 0.1 m 2 / g. Composite comprising zinc oxide supported on a γ-alumina carrier having a pore size of 55 cm 3 / g or more, an average pore size of 90 to 200 Å and pores having a pore size of 90 to 200 Å occupying 60% or more of the total pore volume. A dehydrogenation catalyst, wherein the carrier supports platinum, tin and at least one alkaline metal selected from the group consisting of Groups 1A and 2A of the periodic table. |
