A molybdenum disulfide and 2D metal-organic framework nanocomposite for improved electrocatalytic hydrogen evolution reaction

Abstract The development of electrochemically active nanocomposites with excellent hydrogen evolution reaction (HER) is of great significance for clean energy utilization. Herein, a MoS2/Co-MOF nanocomposite assembled from MoS2 and 2D Co-MOF have been prepared through weak interactions. The optimized nanocomposite exhibits enhanced HER activity, including the lower overpotential (262 mV) and the smaller Tafel slope (51 mV·dec−1), which is attributed to the increased electrochemically active surface area, nanointerface engineering, and the synergistic effect between Co-MOF and MoS2.
