The invention discloses a monatomic cobalt-loaded carbon nitride catalyst and a preparation method and application thereof, the preparation method comprises the following steps: mixing a mixed solution of 2-methylimidazole and cyanuric acid with a melamine solution, adding a cobalt salt aqueous solution to prepare a cobalt salt-loaded supramolecular precursor, and calcining to obtain the monatomic cobalt-loaded carbon nitride catalyst. The monatomic cobalt loaded carbon nitride catalyst is obtained. According to the preparation method disclosed by the invention, a simple'supramolecular self-assembly-coordination/electrostatic adsorption-calcination 'strategy is adopted, and monatomic cobalt can be firmly and uniformly loaded on carbon nitride, so that the prepared monatomic cobalt loaded carbon nitride catalyst has the advantages of high specific surface area, uniform active sites, high atom utilization rate, good stability and the like; the persulfate activating agent is a novel persulfate activating agent w
