MoS2@HKUST‐1 Flower‐Like Nanohybrids for Efficient Hydrogen Evolution Reactions

A novel MoS2‐based flower‐like nanohybrid for hydrogen evolution was fabricated through coating the Cu‐containing metal‐organic framework (HKUST‐1) onto MoS2 nanosheets. It is the first time that MoS2@HKUST‐1 nanohybrids have been reported for the enhanced electrochemical performance of HER. The morphologies and components of the MoS2@HKUST‐1 flower‐like nanohybrids were characterized by scanning electron microscopy, X‐ray diffraction analysis and Fourier transform infrared spectroscopy. Compared with pure MoS2, the MoS2@HKUST‐1 hybrids exhibit enhanced performance on hydrogen evolution reaction with an onset potential of −99 mV, a smaller Tafel slope of 69 mV dec−1, and a Faradaic efficiency of nearly 100 %. The MoS2@HKUST‐1 flower‐like nanohybrids exhibit excellent stability in acidic media. This design opens new possibilities to effectively synthesize non‐noble metal catalysts with high performance for the hydrogen evolution reaction (HER).
