Abstract: Disclosed are a graded tip cuprous oxide single crystal material and a preparation method and application thereof. A first-level structure of the material is a regular octahedron, a second-level structure of the material is pyramid-shaped tips evenly distributed on the first-level structure, a size of the tip ranges from 40 nm to 180 nm, and a surface coverage degree ranges from 10% to 100%. The preparation method thereof comprises the following steps of: separating out a seed crystal from a mixed solution of copper soluble salt, concentrated brine, and strong alkali in advance to obtain a turbid liquid; and adding a reducing agent into the turbid liquid for seed-induced growth, adding excessive distilled water to dissolve the seed, and filtering, washing and drying to obtain the graded tip cuprous oxide single crystal material.
