Abstract: Developing multifunctional materials for energy and sensing is challenging due to demands for high conductivity, catalytic activity, and structural stability. We report a WSe 2 /Ti 3 C 2 Cl 2 hybrid synthesized via one-step solvothermal growth of WSe 2 nanoflowers on Cl-terminated MXene. The strong interface improves electron transport and active site exposure, achieving excellent hydrogen evolution activity with an overpotential of −0.19 V vs RHE at −10 mA cm −2 . The WSe 2 -rich hybrid delivers an initial discharge capacity of 1255 mAh g −1 as a lithium-ion battery anode, outperforming its individual components. MXene boosts conductivity, while WSe 2 morphology buffers volume changes. For sensing, the hybrid doubles the H 2 O 2 reduction signal of WSe 2 and enables amperometric detection from 1 to 88 μM with a 0.6 μM detection limit. Overall, in situ growth of WSe 2 on MXene offers a scalable route to efficient multifunctional materials.
