dc.description.abstract | Metal–organic frameworks (MOFs) have emerged as a class of crystalline porous material for energy-related applications. Many MOF-based materials are efficient catalysts for hydrogen evolution reactions (HERs). Herein, we illustrate a strategy to modify Co-based MOFs into amorphous molybdenum sulfide (MoSx) via a facial solvothermal method. The modification gives rise to CoMoS phases that reduce hydrogen adsorption energy of catalysts. As a result, MoSx substantially improves the catalytic activity of Co-based MOF for HERs. An optimal sample with 40% MoSx delivered the best HER performance with a low onset potential of −147 mV and a Tafel slope of ∼68 mV decade−1. Furthermore, the composite catalyst was stable for up to 1000 cycles without any changes in performance. These results suggest that the MoSx/Co–MOF–74 composite is a viable candidate for replacing noble metals as a high-performance catalyst for HER in the future. © 2020 Elsevier B.V. | - |
