Formatted abstract
Pd nanoparticles modified MoS2 nanoflowers assembled by lamellar nanosheets have been successfully synthesized by a facile hydrothermal method. They were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM, Nanoscope III), X-ray photoelectron spectroscopy (XPS), and evaluated as electrochemical catalysts for hydrogen evolution reaction (HER). It was found that Pd modified MoS2 (MoS2–Pd) without calcinated treatment exhibited high HER activity. The HER activity of this catalyst can be improved after visible-light irradiation. As a novel HER catalyst, the MoS2–Pd under illumination exhibited the best activity with the highest TOF value (0.013 s−1) and the lowest Tafel slope (39 mV dec−1). The results indicate that noble metal Pd plays an important role in promoting the HER activity. The increasing creation of electrons by visible-light irradiation is favorable for the electrochemical hydrogen adsorption reaction, which leads to more hydrogen formation. This work demonstrates the feasibility of increasing HER activity of MoS2-based catalysts by combining MoS2 with Pd noble metal nanoparticles.
