The photocatalytic cooperative hydrogen evolution and alcohol oxidation process for producing of two valuable products is highly attractive strategy, but optimizing active sites and constructing dual-function photocatalysts with high activity and selectivity remains challenging. In this study, dual active sites photocatalysts of Co/N-doped graphitic carbon nanocages (CoNC)/ZnIn 2 S 4 nanosheets (ZIS) were successfully prepared, where the Co atom anchoring on N-doped carbon (Co-N structure) and Co nanoparticles (Co NPs) encapsulating in layered graphitic carbons, resulting in the simultaneous photocatalytic hydrogen production and selective oxidation of benzyl alcohol to benzaldehyde. After regulating the active sites ratio of Co NPs/Co-N, the CoNC/ZIS exhibited an excellent hydrogen production rate (2334 μmol g⁻¹h⁻¹) and benzaldehyde production yield (2825 μmol g⁻¹h⁻¹), which were 9.0 times and 17.5 times than that of pure ZIS, respectively. The characterization results indicated that the Co-N structure served as electron-rich sites and Co NPs served as sites for dehydrogenation, promoting directed electron-hole migration and providing sufficient the optimum reaction sites for hydrogen evolution and benzyl alcohol oxidation. Furthermore, the CoNC optimized structure and interface environment of ZIS, by reducing the potential of the valence band edge and enhancing the adsorption energy for benzaldehyde, thereby effectively improving the selectivity for benzaldehyde (increased from 47.9 % to 99.2 %). Based on DFT calculations, that the synergy of interfacial Co-N structure and Co NPs played a critical role in the coupled photocatalytic system and enhanced photogenerated carrier utilization. This study suggests new avenues to the design of a dual-function photocatalyst for significantly improve the utilization efficiency of solar energy. • A dual-functional photocatalyst was prepared for H 2 evolution coupling with benzyl alcohol selectivity oxidation. • Co-N structure promoted electron enrichment and H 2 evolution, while Co NPs served as sites for dehydrogenation. • CoNC optimized structure and interface environment of ZIS, effectively improving the selectivity for benzaldehyde. • The coupled system achieved the and directed migration and full utilization of electron holes.

This study presents a novel nonradical catalytic oxidation system for targeted p-hydroxybenzene sulfonate (PHS) production from sulfonamides (SAs). A positive external electric field was applied to induce the in-situ activation of O 2 on Mn-doped Co 3 O 4 surface, with Mn-doping used to manipulate the reactivity of surface complexes. Theoretical simulations predicted CoMn-peroxides as thermodynamically favorable candidates for the targeted PHS production. Experimental validation achieved PHS yields of 18.4–32.6 % from five typical SA compounds. While 1 O 2 also actively participated in the oxidation of SAs, disruption of the 1 O 2 oxidation pathway significantly enhanced the PHS yields to 47.6–50.3 %. The intensity of electric field regulated the O 2 activation pathways by influencing the stability of CoMn-peroxides. This nonradical catalytic oxidation system demonstrated excellent catalyst reusability and environmental robustness for energy-efficient SAs removal and PHS recovery. These findings provide new insights into leveraging nonradical = pathways to advance catalytic oxidation technology for sustainable water management. • A nonradical catalytic oxidation system relying on surface complexes is developed. • Targeted p-hydroxybenzene sulfonate production from sulfonamides is achieved. • O 2 is activated into peroxo-species on Mn-doped Co 3 O 4 under electric stimulation. • DFT calculation proves metal-doping could control reactivity of peroxo-species. • Electric field affects stability of peroxo-species and regulates their reactivity.
