In 2D nanomaterials like Transition Metal Dichalcogenides (TMD) exfoliated using liquid exfoliation methods, the solvent will play an important role in determining the final thickness and quality of layers we get out of this process. For instance, Gas sensors based on 2D materials like Molybdenum ditelluride can be prepared by exfoliating single or few layers of MoTe2 from the bulk crystal using liquid exfoliation by probe sonication, this process needs the 2D material powder to be dispersed in specific solvents before being sonicated. In this regard the chosen solvent should have low surface tension and low boiling point, the boiling point of the solvent will play a vital role for the usage of the yielded exfoliated nanosheets in Gas Sensing applications. For that, what are the preferred solvents when exfoliation MoTe2 powders using Liquid exfoliation for the application of Gas Sensors.

  • $\begingroup$ You might want to elaborate a little as some people who can be knowledgeable about one aspect of your question (liquid exfoliation) may not be particularly familiar with the application you have in mind (Gas Sens?), or vice-versa. $\endgroup$ – Buck Thorn Oct 30 '19 at 9:13
  • $\begingroup$ Ok, that update should help. $\endgroup$ – Buck Thorn Oct 30 '19 at 10:56
  • $\begingroup$ the main property of the exfoliated material in Gas Sensors is that the boiling point is not very high so that the solvent could be totally removed after the exfoliation is done $\endgroup$ – キツネ Oct 30 '19 at 11:00
  • $\begingroup$ The crowd here can be tough sometimes. I can only guess that they would like more information on what the solvent properties should be to match your application :-\ $\endgroup$ – Buck Thorn Oct 30 '19 at 17:20
