The invention relates to a high-selectivity alkane alkenyl aromatic hydrocarbon catalyst prepared by dehydrogenating alkyl aromatic hydrocarbon, in particular to a styrene catalyst prepared by dehydrogenating phenylethane. The catalyst takes iron-potassium-cerium-molybdenum as a main system, and is characterized by comprising the following main active components by mass percentage: 1) 50 to 85 percent of Fe2O3; 2) 7 to 15 percent of K2O; 3)1 to 6 percent of MoO3; 4) 2 to 13 percent of CeO2; 5) 1 to 6 percent of MgO; 6) 0.5 to 5 percent of CaO; and 7) 0.05 to 0.9 percent of La2O3. The catalyst prepared especially when iron oxide consists of pigment-grade iron oxide red containing no crystal water and pigment-grade iron oxide yellow containing one crystal water in certain proportion and when potassium oxide and iron oxide are selected within a certain proportion range, has the advantages of maintaining high selectivity and simultaneously raising conversion rate so as to obtain high once through yield of styrene.
