2024年1月20日 · The improved performance of 1T@2H-MoS2 can be accredited to its wide absorption in solar spectrum, effective charge separation, and increased active sites resulting from the 1T phase incorporation. The photocatalytic activity of 2H-MoS2 shown 73% and 1T@2H-MoS2 exhibits 98% methylene blue dye degradation in 60.0 min and5.0 min under ...

2018年4月2日 · Here, we report the large-scale preparation of micrometre-sized metallic-phase 1T ′ -MoX 2 (X = S, Se)-layered bulk crystals in high purity. We reveal that 1T′-MoS 2 crystals feature a...

2019年3月1日 · A stable preparation of 1T MoS 2 in 1T@2H-MoS 2 and 1T@2H-MoS 2 /Au from hydrothermal synthesized 2H-MoS 2 was succeed by Li intercalation. The results of XRD, Raman spectra and XPS confirmed that the bulk MoS 2 undergoes a phase transition and a stable 1T phase was stabilized by Li intercalation [31] , [32] .

2023年11月10日 · Consistent evidence of a partially reversible 2H-1T' transition using in situ Raman spectroscopy where the phase change occurs in the topmost layers of the MoTe2 flake were found. A thickness-dependent transition voltage where higher voltages are necessary to drive the phase change for thicker flakes were found.

2018年8月20日 · Here we demonstrate a controllable and scalable 2H to 1T phase engineering technique for MoS 2 using microwave plasma. Our method allows lithographically defining 1T regions on a 2H...

2022年12月5日 · The amorphous MoCoS x skeleton modified with heterocrystalline phase (1T/2H)–MoS 2 nanostructures exhibit good electrocatalytic performance and stability due to the synergistic effect of the excellent electrical conductivity of the …
