2021年7月22日 · Here, the light-induced efficiency of electrochemically exfoliated TaS 2 nanosheets for hydrogen generation catalysis and photodetectors was demonstrated. Mutual twisting of the exfoliated...

The results showed, high electrical conductivity, the better property of charge transfer, and good transparency layer in the visible region (400–900 nm) with 2H–TaS2 thin film.

Bulk 2H-TaS 2 is an archetypal transition metal dichalcogenide supporting charge density waves with a phase transition at 75 K. Here, it is shown that charge density waves can exist in exfoliated monolayer 2H-TaS 2 and the transition temperature can reach 140 K, …

2016年3月17日 · Polycrystalline 2H-TaS 2 was synthesized by heating stoichiometric quantities of Ta and S in an evacuated quartz ampoule at 900 °C for 9 days. The growth of large single crystals from the ...

2023年4月18日 · The morphology of the 2H-TaS 2 flakes was characterized using SEM, transmission electron microscopy (TEM), and AFM. Figure 3 b shows the SEM image of the exfoliated 2H-TaS 2 nanosheets, which indicates that …

2023年2月15日 · TaS2 ultrathin nanosheets combined with phase engineering and defect engineering have better HER activity and stability. DFT studies show that the addition of 2 H phase structure and rich defects improves the intrinsic activity of TaS2.

2015年11月16日 · Two-dimensional metallic transition metal dichalcogenides (TMDs) are of interest for studying phenomena such as charge-density wave (CDW) and superconductivity. Few-layer tantalum diselenides (TaSe...

1992年10月1日 · The layered compound 2H-TaS 2 is one of the typical materials which lead to charge density waves. However, much less information is available on the superconducting properties of this compound. The Meissner effect in 2H-TaS 2 was studied systematically with special emphasis on

2023年5月9日 · 采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)和原子力显微镜(AFM)对2H-TaS₂纳米片的形貌和厚度进行了表征(图3b-d)，显示2H-TaS₂纳米片具有大的横向尺寸(0.5–11μm)，厚度为单层或少层。

Herein, we report the liquid-phase exfoliation of the 2H-TaS 2 crystals by using 2-propanol to produce single/few-layer (1H/2H) flakes, which are afterward deposited as catalytic films. A thermal treatment-aided texturization of the catalytic films is used to increase their porosity, promoting the ion access to the basal planes of the flakes ...
