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. [ABSTRACT FROM AUTHOR]

In this study, Z-scheme 0D/1D BiVO 4 /CdS nanostructure was successfully prepared with outstanding performance toward photocatalytic enrofloxacin (ENR) removal process. The best performance was gained on BVO/CdS-2 sample (k = 0.0313 min−1), which was 3.3 and 8.7 times higher than that of pure CdS and BiVO 4 samples, respectively. The obtained dot-on-rod architecture exhibited improved separation efficiency of photo-excited electron-hole pairs owing to the rapid transfer of charge carriers. The Z-scheme transfer was also confirmed via electron spinning resonance (ESR) analysis with the generation of both·OH and·O 2 -. This paper could supply new insights into the fabrication of Z-scheme nanostructure with highly efficient toward photocatalytic environmental remediation.

In this study, a series of Ir/WO 2.72 nanoarchitectures were fabricated through solvothermal method. The optimal Ir/WO 2.72 exhibits highly photocatalytic activity and stability for antibiotic photodegradation under visible light irradiation (k = 0.0275 min−1 for 2% Ir/WO 2.72 , 12.5 times higher than that of pristine WO 2.72). The electrochemical performance suggests that the Ir/WO 2.72 hybrid exhibited superior properties in spatial charge separation and transfer. Moreover, Ir could act as active sites for catalytic reaction and light harvesting. The intrinsic properties of Ir/WO 2.72 were tuned and modified based on the characterization results. Besides, the proposed mechanism on Ir/WO 2.72 was also discussed to reveal the key factors for the enhancement of photocatalytic performance. We hope this study could supply new insights toward the utilization of antibiotic wastewater treatment on WO 2.72 -based photocatalysts. [Display omitted] • Ir/WO 2.72 nanoarchitectures were prepared successfully through solvothermal method. • The Ir/WO 2.72 samples possessed excellent performance in photocatalytic tetracycline (TC) degradation. • The ·OH active species was confirmed to play important roles in Ir/WO 2.72 during photocatalysis process.
