    One-Step Synthesis of MoS2/TiSi2 via an In Situ Photo-Assisted Reduction Method for Enhanced\nPhotocatalytic H2 Evolution Under Simulated Sunlight Illumination
    Research 2019 : July - September

    A new MoS2/TiSi2 complex catalyst was designed and synthesized by a simple one-step\nin situ photo-assisted reduction procedure. The structural and morphological properties of the\ncomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM),\nscanning electron microscopy (SEM), and ultraviolet-visible diffused reflectance spectroscopy\n(UV-vis DRS), which proved the formation of MoS2/TiSi2. MoS2/TiSi2 with optimized composition\nshowed obviously enhanced photocatalytic activity and superior durability for water reduction to\nproduce H2. The H2 generation rate over the MoS2/TiSi2 photocatalyst containing 3 wt %MoS2\nreached 214.1 micromole.h^-1.g^-1 under visible light irradiation, which was ca. 5.6 times that of the\npristine TiSi2. The improved photocatalytic activity of MoS2/TiSi2 could be related to the broad\nresponse spectrum, large visible light absorption, and synergies among MoS2 and TiSi2 that enhance\nphotoexcited charge transfer and separation.
