The invention discloses a Ptq/Snq-Fe2O3 catalyst for efficient catalytic degradation of VOCs (volatile organic compounds) as well as a preparation method and application of the Ptq/Snq-Fe2O3 catalyst. The preparation method comprises the following steps: by taking Fe2O3 as a carrier, inducing Sn doping and defect generation through primary quenching to form Snq-Fe2O3; and then, by taking Snq-Fe2O3 as a carrier, inducing Pt clusters to be loaded on the Sn-Fe2O3 through a secondary quenching method to form Ptq/Snq-Fe2O3. Compared with traditional solvothermal methods and the like, the preparation method is simple and high in repeatability. The surface electronic structure of the carrier Fe2O3 can be adjusted through quenching and Sn doping, and the surface physicochemical properties of the carrier are optimized; an active center Pt is introduced in a quenching loading mode, coordination and electronic structures of Pt clusters can be adjusted through interaction between the optimized carrier and the platinum cl
