no. 1 approach
[0073] Preparation of TiS 2 nanoparticle approach
[0074] First, 90 μl of TiCl 4 and 3 g of refined oleylamine were put into a flask, and then heated at a temperature of 300° C. in an argon atmosphere. At this temperature, 0.12 ml of carbon disulfide was mixed. Then, the liquid mixture was heated at a temperature of 300°C.
[0075] After the liquid mixture was maintained at 300° C. for 30 minutes, the liquid mixture was cooled to normal temperature, and then 20 ml of acetone was added to precipitate layered structure nanoparticles. The precipitated layer-structured nanoparticles were collected using a centrifugal separator.
[0076] Then, 20 μl containing the collected TiS 2 The solution of nanoparticles was dropped onto a TEM grid coated with a carbon grid and dried for about 20 minutes. Then, observation was performed by a transmission electron microscope (EF-TEM) (Zeiss, accelerating voltage: 100 kV). figure 2 Observations are shown.
[0077] like figure 2...
no. 2 approach
[0088] Preparation of ZrS 2 nanoparticle approach
[0089] Prepare ZrS by the same method as the first embodiment 2 nanoparticles. In this embodiment, using ZrCl 4 instead of TiCl 4 in order to produce ZrS 2 nanoparticles.
[0090] Figure 7 shows that ZrS prepared in such a way 2 TEM observation of nanoparticles.
no. 3 approach
[0092] Prepare WS 2 nanoparticle approach
[0093] WS is prepared by the same method as the first embodiment 2 nanoparticles. In this embodiment, using WCl 4 instead of TiCl 4 in order to generate WS 2 nanoparticles.
[0094] Figure 8 shows that WS prepared in such a way 2 TEM observation of nanoparticles.
