Hierarchical Electrodes of MoS 2 Nanoflakes Wrapped on CNTs in Wood-Derived Porous Carbon Frameworks for a High-Performance Hydrogen Evolution Reaction

“…The peaks at 276.1, 373.6, and 402.3 cm −1 are associated with the E 1g , E 2g 1 , and A 1g vibration modes of 2H-MoS 2 , respectively, 27 while the peaks at 150.9, 219.8, and 336.0 cm −1 are attributed to the J1, J2, and J3 vibrational modes of 1T-MoS 2 , respectively. 38 The peak at 118 cm −1 is ascribed to the stretching vibrations of Mo-Mo in 1T-MoS 2 . 33 Similar peaks are also identified in Fe/Fe 3 C/CNT@ MoS 2 @GW-2, that is, 2H-and 1T-MoS 2 are simultaneously formed during the hydrothermal reaction.…”

“…Raman spectra of Fe/Fe 3 C/CNT@MoS 2 @GW-2, MoS 2 , and GW are presented in Figure d. The peaks at 276.1, 373.6, and 402.3 cm –1 are associated with the E 1g , E 2g 1 , and A 1g vibration modes of 2H-MoS 2 , respectively, while the peaks at 150.9, 219.8, and 336.0 cm –1 are attributed to the J1, J2, and J3 vibrational modes of 1T-MoS 2 , respectively . The peak at 118 cm –1 is ascribed to the stretching vibrations of Mo-Mo in 1T-MoS 2 .…”

Optimizing graphene content in scaffolds for evenly distributed crumpled MoS2 paper wads as anodes for high-performance Li-ion batteries

“…Moreover, uniform 3D nanostructure distribution enhances active material utilization, boosting overall energy density and reducing the occurrence of undesirable lateral reactions in concentrated regions. In essence, prioritizing uniformity in 3D nanostructure distribution stands as a fundamental strategy for advancing reliability, efficiency, and long-term cyclic stability, which are crucial for specifically LIBs [28][29][30]. Optimization of the RGO content within a composite material for achieving a uniform distribution of MoS 2 nanoflowers is crucial for improving the LIB performance.…”

N-doped Fe2(MoO4)3-decorated MoO3 nanorods via metal–organic framework-involved synthesis as a bifunctional nanoreactor for capturing and catalyzing polysulfides in lithium–sulfur batteries

“…2b, the absorption band of Li 2 S 6 shows a platform around 450 nm. 3,21 After 6 hours, the characteristic absorption band of Li 2 S 6 disappeared, which proved that almost all soluble Li 2 S 6 in the solution was absorbed by N-MoO 3 @Fe 2 (MoO 4 ) 3 . Fig.…”
