英文摘要	hydrogen is considered as an important clean energy carrier for the future, and electrocatalytic splitting of water is one of the most efficient technologies for hydrogen production. as a potential alternative to pt-based catalysts in hydrogen evolution reaction (her), two-dimensional (2d) molybdenum sulfide (mos2) nanomaterials have attracted enormous research interest, while the structure control for high-performance her electrocatalysis remains a considerable challenge due to the lack of efficient preparation techniques. herein, we reported a one-pot chemical method to directly synthesize 2d mos2 with controllable layers. multiple-layer mos2 (ml-mos2), few-layer mos2 (fl-mos2) and single-layer mos2 coating on carbon nanotubes (sl-mos2-cnts) can be efficiently prepared through the modulation of experimental conditions. the enhanced catalytic activity in her is demonstrated by reducing the layer number of mos2 nanosheets. remarkably, the optimized sl-mos2-cnts sample showed long-term durabilitywith an accelerated degradation experiment even after more than 10 000 recycles, and high her activity with an onset over-potential of only similar to 40 mv vs. rhe. this study introduces a novel, cheap and facile strategy to prepare layer-controlled 2d mos2 nanosheets in a large quantity, and is expected to broaden the already wide range energy applications of 2d mos2 nanosheets.
