Incorporating visible light into sulfide oxidation is an emerging desirable strategy to produce versatile sulfoxides. We introduce the design and synthesis of multilayered wrinkled C₃N₄ nanosheets and demonstrate their unprecedented sulfide oxidation activity. Due to the wrinkled surfaces with a large S_BET (208.6 m²g⁻¹), wrinkled C₃N₄ nanosheets exhibit a sensitive optical response, facilitating the electron photoexcition. Layer structure confinement enables robust e⁻-h⁺ interactions and valid photoexcited excitons formation, allowing rapid ¹O₂ reactive species production. Integrating the sensitive optical response with robust e⁻-h⁺ interactions, photoexcited electrons and excitons are jointly produced, giving large yields of ⋅O₂⁻ and ¹O₂ reactive species that are conductive to O₂⁻ and ¹O₂ cocatalysis with an activity that is up to 33-fold that of bulk C₃N₄. In the cocatalysis mechanism, both O₂⁻ and ¹O₂, can produce peroxysulfoxide intermediates, resulting in target sulfoxides. This is the first report on sulfide oxidation via O₂⁻ and ¹O₂ cocatalysis and a promising study on catalyst exploitation for high-efficiency and high-selectivity production process.
