近日,中国科学院上海硅酸盐研究所、北京大学、上海交通大学和华中科技大学的研究者通过低温拓扑化学法成功制备出高质量的1T''' MoS2晶体,他们利用单晶衍射仪解析出1T''' MoS2的晶体结构,并且发现该结构具有不对称中心和非线性光学性质。在隧道扫描显微镜下可以清晰地观察到1T''' MoS2中每三个Mo原子聚集成一个三角形...
The method includes performing phase transition from a 2H crystal structure of MoS to the 1T crystal structure by reacting MoS having the 2H crystal structure with CO gas. The phase transition includes annealing the MoS having the 2H crystal structure in an atmosphere including CO gas.JOO Young ...

Metallic 1T phase molybdenum disulfide (1T-MoS2) holds great promise in energy storage applications due to its excellent conductivity and hydrophilicity. However, free 1T-MoS2 nanosheets are prone to agglomeration and convert to 2H-MoS2, resulting in a decrease in electrochemical performance. In this...
MoS2crystals feature a distorted octahedral coordination structure and are convertible to 2H-MoS2following thermal annealing or laser irradiation. Electrochemical measurements show that the basal plane of 1T′-MoS2is much more active than that of 2H-MoS2for the electrocatalytic hydrogen evolution ...
In the architecture, fallen leaf-like MoS2 nanosheets with a mixed-phase crystal containing 1T and 2H phases grow tightly on the surface and interlayer of Ti_3C_2 matrixes. The expanded layer spacing of Ti_3C_2 as a result of MoS_2 insertion can greatly accelerate electronic/sodium ion ...
The first-shell Ni–O and second-shell Ni–Ni distances both fit to values within the uncertainty of the published crystal structure that was used for the model70. The structural parameters around Ni atoms of NiO@1T-MoS2 as a function of synthesis temperature were fit using the same model ...
MoSe2 is a promising earth-abundant electrocatalyst for the hydrogen-evolution reaction (HER), even though it has received much less attention among the layered dichalcogenide (MX2) materials than MoS2 so far. Here, a novel hydrothermal-synthesis strategy is presented to achieve simultaneous and ...
(0.4 Å in each layer side) of electron density into the vacuum. The 0.8 Å is derived from the first-principles calculated layer thickness for 1H-MoS2(ref.49). MSe2and MTe2may have different decay lengths than MS2. However, such difference should be less than one time of ...
MoS2. The crystal alignment between Co nanodisks and MoS2nanosheets is that the contact layer of Co was covalently bonded with the S atom on the surface of MoS2, and also the contact layer of MoS2nearest to Co nanodisks shows a phase transformation from 2H to distorted 1T phase. We can ...
