The invention discloses a bipolar membrane containing a MoS2 intermediate catalyst layer and a preparation method of the bipolar membrane. The bipolar membrane containing the MoS2 intermediate catalyst layer comprises a cation exchange layer, an anion exchange layer and the MoS2 intermediate catalyst layer, and the intermediate catalyst layer is prepared by the following steps: (1) uniformly mixing MoS2, PVDF powder, carbon black and DMAc to obtain a mixture, coating a copper sheet with the mixture, drying the mixture to obtain a cathode, and taking a graphite rod as an anode to construct an electrochemical cell, dissolving tetraheptylammonium bromide in acetonitrile to serve as an electrolyte solution, applying voltage to perform electrochemical reaction, stripping, dispersing, centrifuging and washing substances on the surface of a copper sheet to obtain a MoS2 catalyst after the reaction is finished, coating a cation exchange layer with a MoS2 catalyst dispersion, and drying to obtain the MoS2 intermediate
