“…At present, O‐doped electrocatalysts are normally fabricated via i) low‐temperature pyrolysis [ 126 ] and ii) hydrothermal method. [ 19,127 ] It also should be noted that oxygen surface doping is actually very difficult to be avoid in some non‐noble metal‐based compounds resulted by partial oxidation with the oxygen in air.

Electrocatalytic water splitting for hydrogen production is an appealing way to reduce carbon emissions and generate renewable fuels. This promising process, however, is limited by its sluggish reaction kinetics and high‐cost catalysts. Construction of low‐cost and high‐performance non‐noble metal‐based catalysts have been one of the most effective approaches to address these grand challenges. Notably, the electronic structure tuning strategy, which could subtly tailor the electronic states, band structures, and adsorption ability of the catalysts, has become a pivotal way to further enhance the electrochemical water splitting reactions based on non‐noble metal‐based catalysts. Particularly, heteroatom‐doping plays an effective role in regulating the electronic structure and optimizing the intrinsic activity of the catalysts. Nevertheless, the reaction kinetics, and in particular, the functional mechanisms of the hetero‐dopants in catalysts yet remains ambiguous. Herein, the recent progress is comprehensively reviewed in heteroatom doped non‐noble metal‐based electrocatalysts for hydrogen evolution reaction, particularly focus on the electronic tuning effect of hetero‐dopants in the catalysts and the corresponding synthetic pathway, catalytic performance, and activity origin. This review also attempts to establish an intrinsic correlation between the localized electronic structures and the catalytic properties, so as to provide a good reference for developing advanced low‐cost catalysts.

“…8,24,[26][27][28] Therein, vertical MoS 2 nanosheets, which have vertical channels for ion penetration and intimate contact between the active nanosheets and the random substrate, were shown to remarkably increase the density of edge sites and hence considered as an ideal geometry for improving the HER performance of MoS 2 -based HER catalysts. 9,22,[29][30][31][32][33][34][35][36][37][38][39][40][41] Although extensive efforts have been made to increase the number of edge sites, the overall HER activity is still limited, as generally only a small fraction of edge sites contribute to the reaction rate. 10,42 Therefore, it is necessary and urgent to explore effective methods to increase the HER activity of inert basal plane sites in MoS 2 nanosheets.…”

“…However, there is still a big gap compared with Pt catalyst. Therefore, great efforts have been made to improve the electrocatalytic activity of MoS 2 , including phase transformation (Tang and Jiang, 2016 ; Jiao et al, 2018 ; Wang J. et al, 2018 ), defect engineering (Xie et al, 2013a , 2017 , 2019 ; Xie and Yi, 2015 ), nanocrystallization (Yun et al, 2017 ), doping (Xie et al, 2013b , 2016 ; Sun et al, 2014 , 2018 ; Xiong Q. et al, 2018 ), modification (Benson et al, 2017 ; Wang Q. et al, 2018 ) and compounding (Jayabal et al, 2017 ; Zhai et al, 2018 ), etc.…”

Energy and environmental issues raise higher demands on the development of a sustainable energy system, and the electrocatalytic hydrogen evolution is one of the most important ways to realize this goal. Two-dimensional (2D) materials represented by molybdenum disulfide (MoS2) have been widely investigated as an efficient electrocatalyst for the hydrogen evolution. However, there are still some shortcomings to restrict the efficiency of MoS2 electrocatalyst, such as the limited numbers of active sites, lower intrinsic catalytic activity and poor interlayer conductivity. In this review, the application of monolayer MoS2 and its composites with 0D, 1D, and 2D nanomaterials in the electrocatalytic hydrogen evolution were discussed. On the basis of optimizing the composition and structure, the numbers of active sites, intrinsic catalytic activity, and interlayer conductivity could be significantly enhanced. In the future, the study would focus on the structure, active site, and interface characteristics, as well as the structure-activity relationship and synergetic effect. Then, the enhanced electrocatalytic activity of monolayer MoS2 can be achieved at the macro, nano and atomic levels, respectively. This review provides a new idea for the structural design of two-dimensional electrocatalytic materials. Meanwhile, it is of great significance to promote the study of the structure-activity relationship and mechanism in catalytic reactions.
