MoS₂ nanosheets decorated with gold nanoparticles for rechargeable Li–O₂ batteries

Abstract

MoS2 nanosheets decorated with gold nanoparticles show enhanced specific capacity and cycle efficiency for rechargeable Li–O2 batteries.

Piezo‐Catalytic Effect on the Enhancement of the Ultra‐High Degradation Activity in the Dark by Single‐ and Few‐Layers MoS2 Nanoflowers

“…In addition, the S2p is positioned at 163.3 for S 2p1/2, and 162.1 eV, for S 2p3/2. [ 29,30 ] On the basis of the Raman spectra and the high-resolution transmission electron microscope (HRTEM) images, we concluded that the MoS 2 NFs indeed possess the rich single-and few-layers with an abundant amount of active edge sites.…”

Production of monolayer-rich gold-decorated 2H–WS2 nanosheets by defect engineering

“…In addition to the functionalisation routes involving the addition of organic molecules, 20,21 it has been shown that CE-1T-TMDs react with AuCl 3 even in the absence of additional reducing agents. [25][26][27][28] As a result, Au 0 is produced and nucleates to form Au nanoparticles (AuNPs). Such TMD-Au hybrids are interesting for a number of applications ranging from rechargeable batteries, 27 to biosensing, 29,30 optoelectronics, [31][32][33] and catalysis.…”

Tailored performance of layered transition metal dichalcogenides via integration with low dimensional nanostructures

“…149 To further improve the cycling stability and rate capability performance of TMDs, integrating LDNs such as Au NPs and TiO 2 NPs is an effective approach. 120,150 Guo et al demonstrated that GQDs/MoS 2 exhibits excellent electrochemical lithium storage properties with a high reversible capacity (1099 mA h g À1 at 100 mA g À1 ), good cyclic stability, as well as excellent rate performance (660 mA h g À1 at 5000 mA g À1 ) as shown in Fig. 6.…”
