Summary: In this study, an amphiphilic Mo/HNT/S nanoreactor was developed by immobilizing MoOx on the internal surface of halloysite nanotubes (HNT) and modifying the external surface with organosilanes. The catalyst exhibited high activity for oxidative desulfurization and showed improved stability over multiple cycles. The amphiphilic nature of the nanoreactor allowed for enhanced dispersion in the oil phase and formation of a concentrated microenvironment for the reactants and reactive oxygen species. This catalytic system eliminates the need for solvent extraction in the desulfurization process, making it a promising candidate for large-scale industrial applications.
