Disclosed are a method of coating the surface of metal oxide with ultrafine metal oxide particles and a coating produced thereby. Specifically, the method of coating the surface of metal oxide with ultrafine metal oxide particles, according to this invention, includes i) bringing metal (M1) oxide into contact with an aqueous solution of a metal (M2) salt to be applied thereon, and ii) continuously mixing and reacting the contacted metal oxide with water at a reaction temperature of 200-700° C. under pressure of 180-550 bar.
