Abstract Efficient photocatalytic production of H 2 from wastewater is expected to address environmental pollution and energy crises effectively. However, the rapid recombination photoinduced carriers results in low photoconversion efficiency. At present, inorganic–organic S‐scheme heterojunction have become a prominent promising technology. In this study, an organic ligand modified MIL‐125‐PDI/ZnIn S 4 (ZIS) catalyst designed. ZIS nanosheets are grown on disc‐shaped MIL‐125‐PDI surface form distinctive hollow nanodiscs with hierarchical structure, giving material abundance active sites, optimized electronic spatially separated redox surface. Consequently, optimal 100MIL‐125‐PDI 250 /ZIS exhibited high HER 508.99 µmol g −1 h Tetracycline hydrochloride (TC‐HCl) solution. Meanwhile, achieved complete TC‐HCl removal mineralization rate 66.62% h. Experimental theoretical calculations corroborate that staggered band alignment work function difference between induce formation built‐in electric field, thus regulating charge transfer routes consequently enhancing separation The possible mechanism analyzed using liquid chromatography‐mass spectrometry (LC‐MS), toxicities degradation products also evaluated. This presents green dual‐function strategy for antibiotic recycling.
