Philips Chidubem Tagbo The basic way to reduce the size of your MoS2 particles is to decrease the concentration of the precursor MoO3. This separates the formed particles and reduces collision frequency thus reducing potential aggregation and agglomeration. Try reducing the concentration of MoO3 by a factor of 10X or 100X to begin with.

Thank you, Professor Alan F Rawle

There are different factors that effect the particle size , but whenever you want to reduce the size of MoS2 so you keep control reaction condition such as Adjust the reaction parameters like temperature, pressure, and time. Fine-tuning these parameters can influence the size and morphology of the MoS2 nanoparticles formed.

The second one is Seeding method;

Introduce small MoS2 seeds into the reaction mixture. These seeds can act as nucleation sites, promoting the growth of smaller nanoparticles.

Post-Synthesis Processing:

Techniques like sonication, ball milling, or other mechanical processes can be employed after the hydrothermal synthesis to further reduce particle size.

Characterization and Optimization:

Utilize techniques like TEM (Transmission Electron Microscopy) or SEM (Scanning Electron Microscopy) to characterize the particle size and morphology. This information can guide further optimization of the synthesis process.
