Lamellar transition‐metal dichalcogenides (MX2) have promising applications in electrochemical energy storage and conversion devices due to their two‐dimensional structure, ultrathin thickness, large interlayer distance, tunable bandgap, and transformable phase nature. Interlayer engineering of MX2 nanosheets with large specific surface area can modulate their electronic structures and interlayer distance as well as the intercalated foreign species, which is important for optimizing their performance in different devices. In this review, a summary on recent progress of MX2 nanosheets and the significance of their interlayer engineering is presented firstly. Synthesis of interlayer‐expanded MX2 nanosheets with various strategies is then discussed in detail. Emphasis is focused on their applications in rechargeable batteries, pseudocapacitors, hydrogen evolution reaction (HER) catalysis and treatments of environmental contaminants, demonstrating the importance of interlayer engineering on controlling performance of MX2. The current challenges of the interlayer‐expanded MX2 and outlooks for further advances are finally discussed.

“…The produced compounds such as intermediate ternary Na x MoO y and Na x WO y [54][55][56] crystalline phase could form and condense on the substrates for subsequent sulfurization. At the beginning, these Na-containing particles which were similar to PTAS and PTCDA [57] seeds could provide nucleation sites on the substrate [58,59] and then were sulfurized into the oxi-chalcogenide nanoparticles encased in a fullerene like shell [53,60].…”

Transition metal dichalcogenides (TMDs) have attracted considerable interest for exploration of next-generation electronics and optoelectronics in recent years. Fabrication of in-plane lateral heterostructures between TMDs has opened up excellent opportunities for engineering two-dimensional materials. The creation of high quality heterostructures with a facile method is highly desirable but it still remains challenging. In this work, we demonstrate a one-step growth method for the construction of high-quality MoS2–WS2 in-plane heterostructures. The synthesis was carried out using ambient pressure chemical vapor deposition (APCVD) with the assistance of sodium chloride (NaCl). It was found that the addition of NaCl played a key role in lowering the growth temperatures, in which the Na-containing precursors could be formed and condensed on the substrates to reduce the energy of the reaction. As a result, the growth regimes of MoS2 and WS2 are better matched, leading to the formation of in-plane heterostructures in a single step. The heterostructures were proved to be of high quality with a sharp and clear interface. This newly developed strategy with the assistance of NaCl is promising for synthesizing other TMDs and their heterostructures.

“…Besides MoS 2 , first time 3D mesoporous MoSe 2 /rGO foam was synthesized by hydrothermal method, which was used as anode in LIB [78]. Additionally, L-TMD NSs such as the SnS 2 and WS 2 have also been combined with the 3D porous structure to improve their electrochemical performance [80][81][82][83][84]. Recently, a facile two-step route to synthesize 3D interconnected graphene frameworks embedded with homogeneously distributed SnS 2 nanoplates (SSG) by using GO NSs, SnCl 4 .5H 2 O and L-cys as source materials has reported.…”

Abstract:With an ever increasing energy demand and environmental issues, many state-of-the-art nanostructured electrode materials have been developed for energy storage devices and they include batteries, supercapacitors and fuel cells. Among these electrode materials, L-TMD (layered transition metal dichalcogenide) nanosheets (especially, S (sulfur) and Se (selenium) based dichalcogenides) have received a lot of attention due to their intriguing layered structure for enhanced electrochemical properties. L-TMD composites have recently been investigated not only as a main charge storage specie but also, as a substrate to hold the active specie. This review highlights the recent advancements in L-TMD composites with 0D (0-dimensional), 1D, 2D, 3D and various forms of carbon structures and their potential applications in LIB (lithium ion battery) and SIB (sodium ion battery).
