The invention discloses a Co3O4-based catalytic material in different coordination environments and a preparation method and application thereof.The preparation method comprises the steps that cobalt salt is dissolved in a mixture of deionized water and ethyl alcohol, ammonia water is added to obtain a transparent solution, then the transparent solution is subjected to a hydrothermal reaction for 3-7 hours at the temperature of 140-170 DEG C, and washing, drying and roasting are conducted to obtain the Co3O4-based catalytic material in different coordination environments. The Co3O4 catalyst with different coordination environments is effectively synthesized by adjusting the adding amount of ammonia water in a precursor in the preparation process. The low-temperature catalytic efficiency of the Co3O4-based catalytic material is greatly improved, the Co3O4-based catalytic material has good propane degradation performance, the synthesis regulation method is simple, the cost is low, and the Co3O4-based catalytic
