The invention discloses a cobalt loaded silica three dimensional fibrous material and a preparation method thereof. According to the preparation method, at first, silica three dimensional fibers are prepared by a static spinning/high temperature sintering technology; then, the silica three dimensional fibers are infiltrated in a cobalt acetate solution and freeze-dried to prepare cobalt loaded silica three dimensional fibers; and through oxidation reactions and reduction reactions, the cobalt composite material loaded on the surface of silica three dimensional fibers is changed to prepare a series of cobalt loaded silica three dimensional fibrous materials with different properties. The prepared cobalt loaded silica three dimensional fibrous material has the advantages that the density is low, the specific surface area is large, and the using amount of cobalt is greatly reduced, and is suitable for the fields such as electric battery, catalyst, catalyst carrier, oil absorption, and the like.
