In this study, an efficient visible light responsive MIL-125(Ti)/ZnIn₂S₄ hybrid structure (MIL-1.2/ZIS) was synthesized through two-step method with improved photocatalytic H₂-evolution performance. The MIL-1.2/ZIS nanocomposites could retained the characteristic features including the highly surface area of metal organic frameworks and the hierarchical sheet-like structure of ZnIn₂S₄. The optimal sample could exhibit the H₂ generation rate of 873.4 μmol g⁻¹·h⁻¹, and the improved photocatalytic activity could be ascribed to the well-matched band structure and the formation of hybrid interfaces, which could lead to the effective charge transfer and separation of photo-excited electron–hole pairs. We hope this paper could broad the potential utilization of MOF-based nanocomposites in photocatalytic energy conversion fields.
