主　　题：molybdenum disulfide dislocation strain hydrogen evolution reaction 

摘      要：Defect engineering is one of the effective strategies to optimize the physical and chemical properties of molybdenum disulfide(MoS_(2))to improve catalytic hydrogen evolution reaction(HER)performance.Dislocations,as a typical defect structure,are worthy of further investigation due to the versatility and sophistication of structures and the influence of local strain effects on the catalytic performance.Herein,this study adopted a low-temperature hydrothermal synthesis strategy to introduce numerous dislocation-strained structures into the in-plane and out-of-plane of MoS_(2)nanosheets.Superior HER catalytic activity of 5.85 mmol·g^(−1)·h^(−1)under visible light was achieved based on the high-density dislocations and the corresponding strain field.This work paves a new pathway for improving the catalytic activity of MoS_(2)via a dislocation-strained synergistic modulation strategy.
