Abstract： Bimetallic ZnCu MOFs and MoS₂ doped ZnCu MOF/MoS₂ materials were synthesized using hydrothermal method. Sodium borohydride reduction method was used to load Pt onto ZnCu MOF/MoS₂ to obtain Pt@ZnCu-MOF/MoS₂ composite material. The morphology， structure， and composition of the composite material were characterized using transmission electron microscopy （TEM）， scanning electron microscopy （SEM）， X-ray diffraction （XRD）， X-ray photoelectron spectroscopy （XPS）， and other testing methods. Methylene blue， Rhodamine 6G， carmine and other dyes were catalyzed by Pt@ZnCu-MOF/MoS₂ to detect their catalytic performance. The results indicated that the prepared Pt@ZnCu-MOF/MoS₂ nanocomposite material achieved catalytic degradation efficiency of 98.8% for MB after 5 min， demonstrating excellent catalytic activity. The catalyst preparation process is simple， the properties are stable， and it is easy to recycle and reuse multiple times.
