I am looking for a place to buy MoS2 nanoparticles, but it should be in a real nanometer size. I bought two materials which were declared as nano but in fact, it was much - much bigger like 2-3 microns. If you have the personal good experience I will be very happy for the help.
As an alternative, I looking for the method for synthesis such small particles of MoS2 but it should be relatively easy and reproducible methods.
My team has long experience with the synthesis of gold and silver nanoparticles. If you will be interested with well characterised AgNP or AuNP and you have nice MoS2 nanoparticles we can exchange our nanomaterials - of course after a discussion about details.
Any help and/or suggestion will be very welcome.

The particles need to be preserved in colloidal suspension, not filtered or dried, to preserve their nano nature. See:

'If the particles are agglomerated and sub-micron it may be impossible to adequately disperse the particles……'The energy barrier to redispersion is greater if the particles have been dried. Therefore the primary particles must remain dispersed in water….'

By the way, did you measure the specific surface area of your materials? How did you conclude that they were 2 - 3 microns?
In my view, it is much more convenient to prepare than to buy nano materials.
Thank you for all answers. I agree with the suggestion that is better to make synthesis in own lab but sometimes is no time and free hands to do everything by yourself.
Hi Grzegorz,
You can buy MoS2 nanoparticles in Alfa Chemistry, and there are kinds of size for you.And the link is here, hope you are satisfied with the anwser. http://www.alfa-chemistry.com/search.aspx?q=mos2
Thank you for all answers.
Finally, I found proper material. When our job will be ready and published I will put information about it on this forum.
Once again Thanks to everybody involved on this topic.
