Zohal Safaei Mahmoudabadi et al.

Summary: The two-dimensional porous MoS2 nanostructure (2D-PMNS) was effectively exfoliated from bulk material using sonication-assisted polyvinyl alcohol (PVA) intercalation, showing potential for increased oxidation desulfurization performance. The nanocatalysts were characterized and used in the oxidation desulfurization process (ODS) of sour gas condensate, with optimization using the Levenberg model and Levenberg-Marquardt algorithm to determine optimum conditions.
