AB  - This study presents the synthesis and characterization of 3D ZnO@MoS<sub>2</sub> nanocomposites, demonstrating their superior performance in photoelectrochemical applications. Employing a combination of hydrothermal and solvothermal methods, the research focuses on creating heterostructures with optimized interfacial characteristics. The ZnO@MoS<sub>2</sub> composites show a substantial increase in photocurrent density (1.02 mA/cm<sup>²</sup>), compared to ZnO nanorods (0.32 mA/cm<sup>²</sup>), underlining enhanced charge separation efficiency. In electrocatalytic hydrogen evolution, the heterostructures exhibit a lower onset potential (-175 mV vs RHE) and reduced Tafel slope (51 mV/dec), indicating improved catalytic activity over MoS<sub>2</sub> nanosheets. Additionally, the composites demonstrate a significant increase in electrochemical capacitance (398 F/g at 10 mV/s), suggesting potential applications in energy storage. These results highlight the efficacy of ZnO@MoS<sub>2</sub> nanocomposites in enhancing solar energy conversion and storage, providing insights into the development of next-generation semiconductor materials.
