The invention discloses a preparation method and application of a photocatalytic material BaTaO2N, and the preparation method of the photocatalytic material BaTaO2N comprises the following steps: S1, mixing and grinding a Ta source, a Ba source and a fluxing agent to obtain a mixture; s2, the mixture is placed in a muffle furnace to be heated, and silver gray powder solid is obtained; and S3, washing the silver gray powder solid with dilute nitric acid and water, carrying out vacuum drying, and grinding to obtain the photocatalytic material BaTaO2N. According to the method, the Ta source and the Ba source serve as precursors, heating treatment is carried out in the presence of the fluxing agent, the high-performance water photolysis photocatalyst BaTaO2N which is low in defect density and high in crystal crystallinity is rapidly synthesized, the preparation process is safe, waste gas treatment is not needed, harsh preparation environments and conditions under the ammonia atmosphere are avoided, the reaction d
