description The invention discloses a Pt-based multi-component catalyst for preparing propylene through propane dehydrogenation, preparation and application of the Pt-based multi-component catalyst. The catalystis composed of a component A, a component B, a component C and a component D, wherein the component A is any one of a transition metal oxide, an alkaline earth metal oxide or a rare earth metal oxide,the component B is elemental Pt, the component C is an oxide of Sn, and the component D is dehydrated alumina. According to the invention, the Pt-based multi-component catalyst which is stable at high temperature, low in carbon deposition coverage and good in durability is accurately prepared by utilizing the interaction of the metal additive, Pt and Sn to realize the high dispersion of the active metal Pt, reduce the reduction of Sn and effectively regulate and control the composition of the multi-component catalyst; and the catalyst prepared by the invention has efficient propane dehydrogenation performance and
