The invention relates to a preparation method and application of a TiO2-SiO2 composite nanofiber supported amorphous alloy catalyst. The preparation method can be sequentially implemented according to the following steps: (1) preparing a TiO2-SiO2 composite nanofiber by taking tetrabutyl titanate and ethyl orthosilicate as raw materials through electrostatic spinning and hot alkali post-processing methods; (2) preparing a solution A by taking a cobalt source and deionized water as the raw materials and dissolving the cobalt source into deionized water; (3) adding the TiO2-SiO2 composite nanofiber to the solution A to form a solution B, and stirring for certain time; (4) carrying out vacuum drying on the solution B to obtain solid powder C; (5) dissolving a boron source into a mixed solution of ethanol and water to obtain a solution D; (6) dropwise adding the solution D to the solid powder C to form a solution E, and stirring and mixing for certain time; and (7) carrying out suction filtration, washing and drying on the solution E to obtain a solid, namely a target product. The preparation method disclosed by the invention has the advantages of simplified process, reduced equipment and low investment cost.
