Electrocatalytic water splitting is considered as a promising technique to produce hydrogen due to its abundant source and environmental friendliness. The development of efficient electrocatalysts for electroca-talytic hydrogen evolution reaction(HER) is highly desirable. With the rise of graphene,two-dimensional (2D)materials have become a potential candidate in water electrolysis due to their unique physical ,chemi⁃cal,and electronic properties. Herein,this review sumarized the recent advances of 2D materials for electro⁃chemical water splitting to produce hydrogen. Firstly,synthesis methods for 2D materials were introduced. Subsequently,strategies to improve the HER performance of 2D materials were summarized. Finally,some challenges and future opportunities in this field were summarized and proposed.
