Product Overview

Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.

The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.

The WS2 provided by Xianfeng is prepared by lithium intercalation method, using n-butyl lithium as intercalation agent to insert lithium ions into the interlayer of WS2, forming LixWS2 intercalation compound. The intercalation compound reacts violently with solvent water to generate a large amount of H2, thereby increasing the interlayer spacing of WS2 and weakening the van der Waals forces between layers. After ultrasonic treatment, thin and few layer WS2 dispersions are obtained. The WS2 nanosheets obtained by lithium intercalation method have a 1T-2H phase hybrid structure. According to XPS calculation, the fitting ratio of 1T phase is about 60% (the values may vary between different batches).

Product Features

1. Good dispersibility: Different types of solvents (water, ethanol, DMF) are available for dispersion, as well as MoS2 powder obtained by freeze-drying the dispersion.

2. Multiple active sites: It has good catalytic performance and a large specific surface area that can be used to load other catalysts to improve catalytic efficiency.

3. Excellent light absorption ability: It has strong absorption ability for visible light and can be used for photocatalytic water splitting to produce hydrogen, organic pollutant degradation, etc.

4. Adjustable size and thickness: Different diameters and thicknesses of nanosheets can be customized to meet the experimental needs of different researchers.


Application Fields

1. Electronic and optoelectronic devices: MoS2 can be used in the manufacturing of transistor electronic devices due to its high electron mobility, large on/off current ratio, and current carrying capacity.

2. Electrochemical biosensors: MoS2 exhibits excellent electrochemical sensing performance due to its large specific surface area, good electron mobility, and high electron density of states,

Can be used to detect biomolecules such as DNA and glucose.

3. Biomedical: MoS2 nanosheets can convert light energy into heat energy, and the high temperature generated can cause tumor cell apoptosis, making them an excellent photothermal conversion material.

4. Lithium ion battery material: MoS2 is an ideal lithium-ion battery material due to its unique layered structure, where weak van der Waals forces combine to facilitate the insertion of lithium ions between the layers.

5. Catalyst: MoS2 nanosheets have the characteristics of large specific surface area and high surface activity, and exhibit good catalytic activity in hydrogenation desulfurization and photocatalytic hydrolysis for hydrogen production.


INSTRUCTION FOR USE

Attention: When taking TEM images, it is necessary to use micro grids (with the thinnest possible thickness) to prepare samples, which makes it easy to observe their layered structure; Dispersed liquid is prone to oxidation when exposed to air, and its color will fade over time. When storing, inert gas can be introduced to remove oxygen and extend the use time; The dispersion liquid will contain lithium hydroxide, which acts as a stabilizer to aid dispersion and can be removed by centrifugal washing; The powder is obtained by freeze-drying the dispersion, and its dispersibility is slightly worse than that of the original solution.

Great toy for chewers!
Style: Tipsy Rosé
This is my dogs favorite toy! He is a super chewer and this has lasted longer than anything. It is also fun to play fetch with and bounces

Long lasting high entertainment toy
Style: Tipsy Rosé
I was gifted one of these for my puppy and it is a fabulous toy. I put in dried liver chunks with at least one that is a bit of a tight fit so it drags out the experience for him. It’s highly durable, gets dragged around and pushed under furniture, and shows tooth marks but is still very effective. I also appreciate it’s easy to clean.

Belgian Mal loves it
Style: Tipsy Rosé
Our Belgian Mal LOVES this toy so much! She hasn’t destroyed it and we got it before Christmas. We put her cookies in it and it keeps her busy for about an hour

Not super chew material
Style: Tipsy Rosé
This is marked as a super chewer. But it’s super flimsy I returned because my dog would destroy it in seconds. If you have a super chewer don’t recommend this toy!

Excellent
Style: Bundle
These are so cute. My Chihuahua couldn’t pull them apart until I got it loose for him. A bigger dog may be able to do this easily. I think that is why he’s wasn’t too impressed with these. As a pet parent, they are a great toy. Extremely well made and excellent quality. Great value as well.
