“…Molybdenum disulfide (MoS 2 ) is the most representative TMD, consisting of hexagonal rings with Mo and S atoms alternately located at the hexagon corners. [56] In 2005, Remškar et al used a high-temperature (1030 K) and catalyzed chemical-transport reaction to synthesize MoS 2 -C 60 composite crystals. [124,125] Despite the extensive reports on the applications of MoS 2 in photocatalytic H 2 production, quite a low photocatalytic activity of MoS 2 has been achieved even for the single-layer MoS 2 since only its edges have the high catalytic activity, whereas its basal plane is inactive.…”

“…In particular, g-C 3 N 4 , with a moderate band gap and indirect-semiconductor nature, has become a promising metal-free catalyst for water splitting and the degradation of pollutants due to the advantages of low cost and high specific surface area (2500 m 2 g −1 for the monolayer) and has been applied in organic solar cells. [56][57][58][59][60] MoS 2 , consisting of hexagonal rings with Mo and S atoms alternately located at the hexagon corners, is the most representative TMD with a direct band gap in monolayer form and high in-plane carrier mobility, thus being suitable for versatile applications in electro and photocatalysis, photovoltaics, and photoelectric devices. Thus, improvements in the photocatalytic activity of g-C 3 N 4 to extend this material to further applications are highly desired.…”

Fullerene has a definite 0D closed‐cage molecular structure composed of merely sp2‐hybridized carbon atoms, enabling it to serve as an important building block that is useful for constructing supramolecular assemblies and micro/nanofunctional materials. Conversely, graphene has a 2D layered structure, possessing an exceptionally large specific surface area and high carrier mobility. Likewise, other emerging graphene‐analogous 2D nanomaterials, such as graphitic carbon nitride (g‐C3N4), transition‐metal dichalcogenides (TMDs), hexagonal boron nitride (h‐BN), and black phosphorus (BP), show unique electronic, physical, and chemical properties, which, however, exist only in the form of a monolayer and are typically anisotropic, limiting their applications. Upon hybridization with fullerenes, noncovalently or covalently, the physical/chemical properties of 2D nanomaterials can be tailored and, in most cases, improved, significantly extending their functionalities and applications. Here, an exhaustive review of all types of hybrids of fullerenes and 2D nanomaterials, such as graphene, g‐C3N4, TMDs, h‐BN, and BP, including their preparations, structures, properties, and applications, is presented. Finally, the prospects of fullerene‐2D nanomaterial hybrids, especially the opportunity of creating unknown functional materials by means of hybridization, are envisioned.

“…11–13 Like most 2D materials, the properties of TMDCs depend on thickness, particularly in the atomically thin limit. 11,12,14–16 In the bulk, TMDCs are layered materials with a stoichiometry of MX 2 , where M represents a group IV, V, or VI transition metal and X represents a chalcogen such as sulfur, selenium, or tellurium.…”

The family of two-dimensional (2D) materials is comprised of a continually expanding palette of unique compositions and properties with potential applications in electronics, optoelectronics, energy capture and storage, catalysis, and nanomedicine. To accelerate the implementation of 2D materials in widely disseminated technologies, human health and environmental implications need to be addressed. While extensive research has focused on assessing the toxicity and environmental fate of graphene and related carbon nanomaterials, the potential hazards of other 2D materials have only recently begun to be explored. Herein, the toxicity and environmental fate of post-carbon 2D materials, such as transition metal dichalcogenides, hexagonal boron nitride, and black phosphorus, are reviewed as a function of their preparation methods and surface functionalization. Specifically, we delineate how the hazard potential of 2D materials is directly related to structural parameters and physicochemical properties, and how experimental design is critical to the accurate elucidation of the underlying toxicological mechanisms. Finally, a multidisciplinary approach for streamlining the hazard assessment of emerging 2D materials is outlined, thereby providing a pathway for accelerating their safe use in a range of technologically relevant contexts.

“…Several review papers have summarized the structure, synthesis, and composites of 2D TMDs, as well as their application in HER [16][17][18][19][20][21]. It is commonly accepted that unique 2D plenary structures provide ultrahigh specific surface area, atomic thickness, and an atomically flat facet [22].…”

Abstract:Recently, transition metal dichalcogenides (TMDs), represented by MoS 2 , have been proven to be a fascinating new class of electrocatalysts in hydrogen evolution reaction (HER). The rich chemical activities, combined with several strategies to regulate its morphologies and electronic properties, make MoS 2 very attractive for understanding the fundamentals of electrocatalysis. In this review, recent developments in using MoS 2 as electrocatalysts for the HER with high activity are presented. The effects of edges on HER activities of MoS 2 are briefly discussed. Then we demonstrate strategies to further enhance the catalytic performance of MoS 2 by improving its conductivity or engineering its structure. Finally, the key challenges to the industrial application of MoS 2 in electrocatalytic hydrogen evolution are also pointed out.
