Abstract Low-temperature KSCN molten salt is a promising technique to synthesize defect-rich MoS 2 catalysts for hydrogen evolution reaction (HER). However, owing the fast ion diffusion rate rapid crystal growth, resultant show morphology of microsphere, which aggregates from nanosheets, suppress catalytic performance. In this work, large-sized few-layer nanosheets are synthesized via spatial confinement strategy by adding inert NaCl into salt. With spacer physically block long-distance and isolate chemical reaction, nucleation subsequent growth could be controlled, guiding grow along narrow gap between crystals avoid aggregation. As result, ultrathin with large geometry size constructed. Profiting architecture expose active sites boost charge transfer kinetics, exhibit an impressive HER performance, showing small η 10 160 mV low Tafel slope 53 dec −1 excellent stability. This work provides not only efficient catalyst but also facile design spectrum transition metal sulfides broad uses.
