The invention relates to a perovskite-type titanium-strontium-cobalt catalyst for hydrogen production by autothermal reforming of acetic acid and a preparation method. The catalyst with resistance tosintering, anti-carbon deposit, oxidation resistance and high activity is provided to aim at solving the problems that an existing catalyst has carbon deposits, sintering and oxidation of active components in the autothermal reforming process of acetic acid, and deactivation of the catalyst is caused. According to the perovskite-type titanium-strontium-cobalt catalyst for the hydrogen production by autothermal reforming of acetic acid and the preparation method, a sol-gel method is adopted to prepare the perovskite-type titanium-strontium-cobalt catalyst, and after calcination, a perovskite composite oxide catalyst Ti<1-x>Sr<x>CoO3 is obtained, wherein x=0-0.8. The perovskite structure facilitates the dispersion of an active component Co, strengthens the synergistic effect between the active component and a carrier, and inhibits the aggregation and growth of Co, thereby obtaining stable small-particle-size Co particles. In addition, Ti is partially replaced with Sr to increase the surface defect position and lattice defect structure of the perovskite-type catalyst, so that the carbon deposit resistance, oxidation resistance and thermal stability of the active component cobalt are improved, the diffusion of acetic acid, water vapor and oxygen is further facilitated, and the catalytic activity is increased.
