Name:Few Layers  Nano MoS2 Suspension 

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.

Very nice but -
Color: Black, Size: 64 oz
Got it today. Just put it to use and made some cold brew. Looks nice and sturdy and doesn’t leak. Has a great large capacity to make a lot of cold brew. Lid closure is great and seals nicely. Very easy to use and user friendly. The plastic material is very thick feeling so that tells me it will withstand quite a bit. I like it so far. My only issue is as soon as I opened the box and pulled the spoon out, it was broken. The bottom stand is completely broken and barely stands up. So that’s disappointing. Otherwise, seems very nice.

Reliable and Easy to Use Cold Brew Coffee Maker
Color: Black, Size: 40 oz, Color: Black, Size: 40 oz
This cold brew maker is easy to use and does the job well. I get smooth coffee every time without bitterness. The size is good and fits in my fridge without taking much space. The filter works well and keeps most of the grounds out of the coffee. Cleaning is simple and does not take much time. The build feels solid for daily use. I like that I can control how strong the coffee is by changing the water and coffee ratio. One thing to know is that you need coarse ground coffee for best results. (I use Bizzy coffee) Letting it steep longer makes the flavor better. It is not insulated, so you should keep it in the fridge while brewing.

Best cold brew brewer out there
Color: Black, Size: 40 oz
One of my favorite purchases in a long time. This coffee maker is just a perfect size and it can be put in the fridge in any direction, on its side, on its top, whatever. It does not leak and it's very easy to clean. Just a superior product all the way around.

Great cold brew maker!
So far this has been a big improvement from a different brand cold brew maker I had. It is simple and easy to used doesn’t leak. The coffee comes out tasting great! It has a smart design that works well. It’s a great deal for how well it works. It is big enough to last all week but not take up to much space in the fridge.

Air gets trapped in the filter so it won’t fully steep
Color: Black, Size: 40 oz
Filter doesn’t let air out. It’s weird about all these positive reviews bc I tried cold brewing tea two times overnight but the filter holes are so small that basically it traps a large air bubble inside with the tea leaves. The water was barely steeped. It was weird enough to the point where I thought there must be a clear film on the filter that I hadn’t removed. When I loosen the lid all do the air rushes out and it fills w water, but when you tighten the lid any air inside with your grounds/leaves is trapped and prevents steeping. I kept thinking it was me based on all of these positive reviews but I could not prevent the massive about of air from getting trapped in the filter. If they made the holes bigger (not too big to let grounds out but currently you could mistake it for plastic film) then it would’ve been perfect. Nice size and about what I’d drink in a day or so. Change the filter hole size to let air flow out and I’ll buy it back!
