“…Introduction of foreign atoms into transition metal compounds can help modulate the electronic structures to improve the HER performances, and the introduced atoms can be cations or anions [112,113]. Wang et al [114] investigated the HER performance of the cobaltdoped FeS 2 NSs/CNTs (Fe 0.9 Co 0.1 S 2 /CNT), and they believed that doping metal atoms can effectively modify the electronic structure, thus optimizing the ΔG H* on the catalyst surface, accelerating the HER process.…”

With the ever-pressing issues of global energy demand and environmental pollution, molecular hydrogen has been receiving increasing attention as a clean alternative energy carrier. For hydrogen production, the design and development of high-performance catalysts remains rather challenging. As the compositions and structures of catalyst interfaces have paramount influences on the catalytic performances, the central topic here has always been to design and engineer the interface structures via rational routes so as to boost the activities and stabilities of electrocatalysts on hydrogen evolution reaction (HER). Here in this review, we focus on the design and preparation of multi-scale catalysts specifically catering to HER applications. We start from the design and structure-activity relationship of catalytic nanostructures, summarize the research progresses related to HER nanocatalysts, and interpret their high activities from the atomistic perspective; then, we review the studies regarding the design, preparation, HER applications and structure-activity relationship of single-atom site catalysts (SASCs), and thereupon discuss the future directions in designing HER-oriented SASCs. At the end of this review, we present an outlook on the development trends and faced challenges of catalysts for electrochemical HER.

“…Transition-metal-based compounds have attracted extensive research interests as alternatives to replace the scarce noble-metal-based electrocatalysts. , Among them, 3d transition-metal (Ni, Co, Fe, and Mn) dichalcogenides have drawn a growing amount of attention because they are earth-abundant and environmentally benign. , As important semiconductors based on 3d transition-metal sulfides, cobalt sulfides (e.g. CoS 2 , CoS, Co 3 S 4 , and Co 9 S 8 ) have been investigated as catalysts due to remarkable advantages of electrochemical activity and chemical stability in both acid and alkaline conditions. − Up to now, considerable research studies have been carried out to stimulate cobalt-sulfide-based catalysts for efficient water splitting to produce H 2 . , For example, Jin et al synthesized the ternary pyrite-type cobalt phosphosulphide for HER . Chen reported the MoS 2 nanosheet-coated CoS 2 nanowire arrays on carbon cloth as an electrode for HER .…”

Although various cobalt-sulfide-based materials have been reported for the hydrogen evolution reaction, only a few have achieved high activity in both acid and alkaline electrolytes due to the inherent poor conductivity and low active sites. In this work, a heterojunction of cobalt sulfide and Mo 2 N is designed for efficient hydrogen evolution reactions in both acid and alkaline electrolytes. X-ray photoelectron spectroscopy reveals that Mo−S bonds are formed at the interface between Mo 2 N and CoS 2 , which result in the fabricated Mo 2 N/CoS 2 materials exhibiting a considerably enhanced hydrogen evolution reaction activity than the corresponding Mo 2 N, CoS 2 , and most reported Mo-and Co-based catalysts in electrolytes of H 2 SO 4 and KOH solutions. Density functional theory calculations suggest that the redistribution of charges occurs at the heterointerface. In addition, the interfacial active sites possess a considerably lower hydrogen adsorption Gibbs free energy than those atoms that are far away from the interface, which is beneficial to the process of hydrogen evolution reaction. This study provides a feasible strategy for designing hetero-based electrocatalysts with a tuned highly active interface.

“…It is proven that the doping or intercalation of ions group can modulate the band structure to improve the electric conductivity and offer more active sites for metal sulfides, thus leading to the enhancement of electrochemical performance. [36,37] Recently, phosphate ion (PO 4 3− ) doping has aroused wide concern due to its large ion radius of ≈2 Å and high electronegativity. On the one hand, the phosphate ion with large ion radius could be introduced into the interlayer as a doping site to enlarge the interlayer spacing of sulfides, which can improve the transfer of Na + .…”

Tin disulfide (SnS2) shows promising properties toward sodium ion storage with high capacity, but its cycle life and high rate capability are still undermined as a result of poor reaction kinetics and unstable structure. In this work, phosphate ion (PO43−)‐doped SnS2 (P‐SnS2) nanoflake arrays on conductive TiC/C backbone are reported to form high‐quality P‐SnS2@TiC/C arrays via a hydrothermal–chemical vapor deposition method. By virtue of the synergistic effect between PO43− doping and conductive network of TiC/C arrays, enhanced electronic conductivity and enlarged interlayer spacing are realized in the designed P‐SnS2@TiC/C arrays. Moreover, the introduced PO43− can result in favorable intercalation/deintercalation of Na+ and accelerate electrochemical reaction kinetics. Notably, lower bandgap and enhanced electronic conductivity owing to the introduction of PO43− are demonstrated by density function theory calculations and UV–visible absorption spectra. In view of these positive factors above, the P‐SnS2@TiC/C electrode delivers a high capacity of 1293.5 mAh g−1 at 0.1 A g−1 and exhibits good rate capability (476.7 mAh g−1 at 5 A g−1), much better than the SnS2@TiC/C counterpart. This work may trigger new enthusiasm on construction of advanced metal sulfide electrodes for application in rechargeable alkali ion batteries.
