This study aims to improve the catalytic oxidation of sulfides to sulfones through enhanced adsorption techniques.
Developed a TiO2 @nitrogen-doped hierarchical porous carbon catalyst via parallel chemical activation.
Synthesized material with a surface area of 2819 m2/g and pore sizes extending from 0.6 to >2.0 nm.
Utilized π–π interactions and applied second-order kinetics and Langmuir–Freundlich models for adsorption studies.
Achieved a turnover frequency of 519 h−1 for oxidizing sulfides to sulfones.
Demonstrated enhanced adsorption led to rapid generation of ·OH radicals, facilitating oxidation reactions.
Confirmed metal-support interactions modified Ti3+/Ti4+ environments, optimizing catalytic performance.
