Product Overview

MoS2 is a typical transition metal disulfide with a two-dimensional layered structure similar to graphene. MoS2 has three crystal structures: 1T type, 2H type, and 3R type. Among them, 1T type and 3R type are metastable phases, and 2H type is stable phase. Macroscopic MoS2 materials mostly exist in 2H type, with a unique sandwich structure, belonging to the hexagonal crystal system structure.
The synthesis methods of MoS2 are mainly divided into two categories: top-down exfoliation method and bottom-up exfoliation method. The top-down exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation. It mainly involves physically exfoliating bulk MoS2 into single or few layered structures. The "bottom-up" stripping method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method. It mainly grows atoms and molecules into nanoscale thin film and granular MoS2 under certain environmental conditions through chemical means.
The molybdenum disulfide provided by Xianfeng is prepared by lithium intercalation method, using n-butyl lithium as the intercalation agent to insert lithium ions into the interlayer of MoS2, forming LixMoS2 intercalation compound. The intercalation compound reacts violently with solvent water to generate a large amount of H2, thereby increasing the interlayer spacing of MoS2 and weakening the interlayer van der Waals force. Then, thin and few layered MoS2 dispersions are obtained through ultrasonic treatment. The molybdenum disulfide nanosheets obtained by lithium intercalation method have a 1T-2H hybrid structure, and according to XPS calculations, the 1T phase ratio is approximately 60% (values may vary between different batches).


Technical Parameter

Appearance: Black solution

Flake Size: 20-500 nm

Stabilizer: LiOH

Product Features

1. Good dispersibility: Different types of solvent dispersions (water, ethanol, DMF) are available for selection, as well as MoS2 powder obtained by freeze-drying the dispersions.
2. Multiple active sites: with good catalytic performance and a large specific surface area, it 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 decomposition of water to produce hydrogen, organic pollutant degradation, etc.
4. Adjustable size and thickness: Nanosheets with different diameters and thicknesses 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 induce tumor cell apoptosis, making them an excellent material for photothermal conversion.
4. Lithium ion battery material: MoS2 is an ideal lithium-ion battery material due to its special layered structure, which is easily inserted by lithium ions in the interlayer due to the combination of weak van der Waals forces.
5. Catalyst: MoS2 nanosheets have the characteristics of large specific surface area and high surface activity, and exhibit good catalytic activity in hydrodesulfurization 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.

A superb addition to the Marvel Darth Vader canon
Format: Paperback
An almost perfect run of comic books, focused around the Imperial assault on Mon Cala post-Episode III. Many familiar faces are here: Vader, of course; Tarkin; Ackbar; Palpatine; Rogue One’s Admiral Raddus; and many more, including Sith, Jedi, and clones (there’s a nice nod to Order 66). Charles Soule deftly weaves an intriguing narrative, fast-paced but also with plenty of depth. The art is also excellent. In addition to the main stretch of the story, the trade also contains the Darth Vader annual, an outstanding Rogue One story that caps things off nicely. Highly recommended reading for Star Wars fans.

Good for Darth vader fans.
Format: Paperback
This book was amazing. I prefribly like vol.4 more than vol.3. The writers of this book have outdone themselves again, another one of Vaders archaic stories and the book was in perfect condition. I highly recommend it.

Charles Soule's Series Continues to Impress and is Arguably the Best of Marvel's New Canon
Format: Paperback
Darth Vader leads the invasion of Mon Cala. With the Empire tightening its grip across the galaxy, Vader is dispatched by his master to the aquatic world of Mon Cala to track down a rogue Jedi who may be advising the planet's king. With the Inquisitors in tow, Vader and Grand Moff Tarkin face off with one of the first open acts of rebellion in their new Empire. Soule is at his absolute best with this series as he continues to explore a version of Vader haunted by his own inner goodness and memories of the past (the book does contain some references to events of the Clone Wars television show, but you don't need to have seen it to grasp the story). Likewise, his exploration of the seduction of the dark side is fantastic with a new Jedi target willing to use deception and war in order to light the sparks of a future rebellion. The final issue of the book may be one of the best Star Wars comics of the entire new canon with Tarkin hunting Vader for sport (on the latter's request oddly enough) across a desolate and hostile planet. The issue isn't what one expects but makes a great deal of sense when exploring the relationship between these two characters (while also explaining why Vader is so deferential to Tarkin during A New Hope). The final addition is a decent annual that sees Vader investigating the Death Star and sabotage of its construction. The annual isn't the best addition to the series (the artwork isn't up to the standards of the rest of the series), but it does introduce some intriguing ideas about Tarkin and Vader's relationship and the events that set up the Rogue One movie.
