The invention discloses a cobalt-doped titanium dioxide photocatalyst as well as a preparation method and application thereof. Cobalt is highly dispersed in nano titanium dioxide in an atomic-scale dispersion form. A cobalt source is introduced in the titanium dioxide lattice growth process and is induced to be uniformly distributed in a titanium dioxide lattice framework through subsequent treatment, the synthesis method is simple, and an additional template agent or an inducer does not need to be introduced. Meanwhile, the electron and chemical structures of doped atoms can be directly regulated and controlled in the synthesis process; through the introduction of metal doping, the number of surface active sites is increased, the carrier density of a semiconductor is improved, the light absorption performance is regulated and controlled by using a doping energy level, the problem of serious carrier recombination of a single titanium dioxide semiconductor can be overcome, and meanwhile, due to the fact that t
