“…Amid the non-HDS approaches, photocatalytic aerobic oxidative desulfurization (PAODS) has emerged as a promising and sustainable approach, which enables gentle operating conditions and remarkable efficiency in converting refractory thiophenic compounds . The viability of PAODS has been substantiated through the development of advanced photocatalysts, such as metal oxides, carbon nitride, and graphene oxides. − Nonetheless, currently reported catalysts still face limitations in terms of photocatalytic efficiency, which can be in a large extent attributed to their narrow light absorption spectra and suboptimal electron–hole separation efficiency. − …”

Photocatalytic aerobic oxidation desulfurization (PAODS) has emerged as a sustainable means for the desulfurization of fuels, which is, however, limited by the low efficiency of electron−hole separation in currently available catalytic systems. In this study, we report the design and synthesis of a ZnIn 2 S 4 quantum dot (QD)/Mo-doped WO 2.72 nanowire 0D/ 1D Z-scheme heterojunction photocatalyst for the PAODS of thiophenic sulfides. We elucidate that the incorporated Mo sites facilitate the localized surface plasmon resonance (LSPR) effect for the generation of hot electrons and also act as high-activity sites for sulfide oxidation. The integration of ZnIn 2 S 4 QDs improves the adsorption of visible light and facilitates the separation of electron− hole pairs. The photocatalyst demonstrates outstanding activity with a mass specific activity of 3.91 mmol g −1 h −1 . In particular, it successfully achieves the deep desulfurization of real diesel, effectively reducing the sulfur content to 9.4 ppm, which suggests its appealing practical potential. These findings offer valuable insights, both from a scientific and practical perspective, to develop high-performance photocatalysts for sustainable PAODS processes.
