This invention provides a two-dimensional MOF / MXene heterojunction, its preparation method, and its applications, relating to the fields of nanomaterial preparation and sensing technology. The method involves transferring large-size two-dimensional MXene nanosheets to a substrate and fixing them on a rotating platform. Under rotation and illumination, a metal salt solution and an organic ligand solution are sequentially added to the MXene surface through a layer-by-layer assembly process. Centrifugal force is used to spread the solution and remove excess liquid. After cyclic reaction, a MOF layer is grown in situ on the MXene surface, forming a MOF / MXene heterojunction. This invention also provides the two-dimensional MOF / MXene heterojunction obtained by the above preparation method. Furthermore, this invention provides the application of the two-dimensional MOF / MXene heterojunction prepared by the above method in the field of sensing and detection. The sensor constructed based on this invention exhibits high sensitivity, low detection limit, and good stability, making it suitable for high-precision sensing and detection.
