electric or solar energy as a driving force is a promising measure to realize the generation of green energy source. [1,2] However, electro-and photocatalytic hydrogen evolution reaction (HER) both confront a big challenge regarding the conversion efficiency and economical cost. [3][4][5][6] There are two general concerns for the two mentioned HER pathway, that is the low charge transport efficiency and surface reactivity. [7][8][9] Therefore, material design to overcome the general shortcomings for HER is urgent to boost the performance.Structural engineering of nanomaterials has been proven as a powerful pathway to tune their physico-chemical and electronic properties, and thus resulting in improved catalytic performance. [10][11][12] Transitional metal dichalcogenides (TMDs) represented by MoS 2 are advancing catalysts for HER, owing to the hydrogen adsorption ability and earth-abundant characteristics. [13][14][15] Recent reported structural engineering strategies for TMDs generally focus
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
