“…The peaks at 161.7 and 162.8 eV in S 2p spectrum separated by a spin-orbit splitting of 1.1 eV were attributed to the S 2− of MoS 2 (Fig. 2d) [28]. All the aforementioned results confirm the formation of MoS 2 on rGO nanosheets.…”

The increasing demand of clean water and effective way to recycle industrial wastewater has offered a new application for carbon-based three-dimensional (3D) porous networks as sorbents due to their superior sorption abilities. Through the surface modification and hybridization with functional materials, the physical and chemical properties of the 3D carbon-based materials can be engineered. In this work, graphene-MoS 2 aerogels (GMAs) with bulky shape are synthesized via a one-pot hydrothermal method. The obtained GMAs show quick sorption rate and high sorption capacity towards a wide variety of contaminants. The sorption covers not only organic solvents or organic dyes, but also toxic heavy metals ions such as Hg 2+ and Pb 2+ . More importantly, the sorption capacity towards metal ions can be optimized by simply changing the loading amount of MoS 2 .

“…The large surface area of two-dimensional (2D) nanomaterials, including sheets and plates, makes them promising for applications in electrochemical and optical fields [89,90]. However, few 2D amorphous nanomaterials have been reported [68,69], which might be because of their limited synthetic methodology.…”

Nanoscale amorphous materials are very important member of the non-crystalline solids family and have emerged as a new category of advanced materials. However, morphological control of amorphous nanomaterials is very difficult because of the atomic isotropy of their internal structures. In this review, we introduce some emerging innovative methods to fabricate well-defined, regular-shaped amorphous nanomaterials. We then highlight some examples to evaluate the use of these amorphous materials in electrodes, and their optical response. There is still plenty of room to explore the amorphous world. As researchers continue to advance the scientific tools that underpin the concepts related to "amorphous", additional applications of these materials will emerge. Their controlled synthesis will undoubtedly attain new heights in the discipline of nanomaterials, and allow nanoscale amorphous materials to become more sophisticated, diverse, and mainstream.

“…45 The Raman spectrum in Figure 2b reveals two dominant peaks located at 373 and 403 cm −1 which could be assigned to the characteristic peaks of inplane E 1 2g and out-of-plane A 1g along the c-axis vibrational modes of hexagonal MoS 2 (Mo−S bonds). 18 The peak intensity related to A 1g vibrational mode is about three times larger than that related to E 1 2g one.…”

Three-dimensional oxygen-incorporated MoS 2 ultrathin nanosheets decorated on reduced graphene oxide (OMoS 2 /rGO) had been successfully fabricated through a facile solvent-assisted hydrothermal method. The origin of the incorporated oxygen and its incorporation mechanism into MoS 2 were carefully investigated. We found that the solvent N,N-dimethylformamide (DMF) was the key as the reducing agent and the oxygen donor, expanding interlayer spaces and improving intrinsic conductivity of MoS 2 sheets (modulating its electronic structure and vertical edge sites). These O dopants, vertically aligned edges and decoration with rGO gave effectively improved double-layer capacitance and catalytic performance for hydrogen evolution reaction (HER) of MoS 2 . The prepared O-MoS 2 /rGO catalysts showed an exceptional small Tafel slope of 40 mV/decade, a high current density of 20 mA/cm 2 at the overpotential of 200 mV and remarkable stability even after 2000th continuous HER test in the acid media.
