Polyolefin and Polystyrene‐Derived Carbon Nanotubes: Catalysts for Oxidative Desulfurization Under a Biphasic System

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Polyolefins and polystyrene, simulating plastic solid waste (PSW), are transformed into value‐added carbon nanotubes (CNTs) through chemical vapor deposition (CVD). The CNTs are then applied in the oxidative desulfurization (ODS) of dibenzothiophene (DBT) in the oil–water biphasic system, resulting in C─S cleavage, yielding sulfur‐free products ...
