description In this work, MoSe<sub>2</sub>-WS<sub>2</sub> nanocomposites consisting of WS<sub>2</sub> nanoparticles covered with few MoSe<sub>2</sub> nanosheets were successfully developed via an easy hydrothermal synthesis method. Their nanostructure and photocatalytic hydrogen evolution (PHE) performance are investigated by a series of characterization techniques. The PHE rate of MoSe<sub>2</sub>-WS<sub>2</sub> is evaluated under the white light LED irradiation. Under LED illumination, the highest PHE of MoSe<sub>2</sub>-WS<sub>2</sub> nanocomposite is 1600.2 µmol g<sup>−1</sup> h<sup>−1</sup>. When compared with pristine WS<sub>2</sub>, the MoSe<sub>2</sub>-WS<sub>2</sub> nanostructures demonstrated improved PHE rate, which is 10-fold higher than that of the pristine one. This work suggests that MoSe<sub>2</sub>-WS<sub>2</sub> could be a promising photocatalyst candidate and might stimulate the further studies of other layered materials for energy conversion and storage.
