FAQ

1. Is it necessary to remove LiOH before filtering MoS2 on the support membrane?

There is a tiny amount of LiOH in the solution. LiOH is soluble in the solution so it will be filtered with the solution when you filter the MoS2 nanosheets using the membrane. There’s no need to remove LiOH before using it on the support membrane.

2. What is the ratio of 2H/1T phases of monolayer MoS2 powder?

About 60%.

3. What is the production process of conductive monolayer MoS2 flakes?

MoS2 reacts with n-Butyllithium to generate LiXMoS2. Li is between the MoS2 layers. The hydrogen produced by the reaction of Li and H2O can expand MoS2. In other words, LIXMoS2 reacts with water to directly generate MoS2 flakes.

4. How can I ultrasonically disperse monolayer MoS2 powder products in water?

If the cold-dried powder is re-dispersed, the dispersion stability will not be very good due to its low oxygen content. It is recommended that the concentration does not exceed 0.1 mg/mL during dispersion. Generally, 30 minutes of ultrasonication of more than 300 watts is sufficient.
