The invention discloses a cobalt-based catalyst and a preparation method and application thereof. Comprising a cobalt element and an alkali metal element; the cobalt element exists in the form of a simple substance, cobalt oxide or cobalt carbide; the alkali metal element is selected from at least one of Li, Na, K, Rb and Cs; the alkali metal element exists in the form of a simple substance; in the cobalt-based catalyst, the total mass of the metal elements is 100 wt%, the content of the cobalt element is 50-99.5 wt%, and the balance is alkali metal elements. The catalyst has high activity and oxygen-containing compound selectivity in Fischer-Tropsch synthesis. The phenomenon of low selectivity of the oxygen-containing compound in Fischer-Tropsch synthesis is effectively solved, and an effective way is provided for improving the selectivity of the oxygen-containing compound.
