Z-Scheme BiOBr/Ti-MOF Nanosheet Heterojunction for Enhanced Visible-Light-Driven Pollutants Degradation

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Март 14, 2025

A Z-scheme photocatalyst could enhance charge separation and extend the photocatalytic activity under visible light, improving efficiency of pollutant degradation other photochemical processes. In this study, a low-energy, high-performance BiOBr/NH2-MIL-125 (Ti) nanosheet (BiOBr/Ti-MOF NS) heterojunction was efficiently synthesized through simple solvothermal method. Under light irradiation, photodegradation rate constant BiOBr/Ti-MOF NS for Rhodamine B (RhB) (k = 0.403 76 min–1) greater than that pure BiOBr 0.089 75 NH2-MIL-125 0.071 67 min–1). The 0.015 58 hexavalent chromium (Cr(VI)) also significantly higher 0.001 70 0.003 72 RhB completely degraded within 6 min, while reduction Cr(VI) reached 79.0% 100 min. Furthermore, possible mechanism in composites is proposed based on structural analysis radical quenching experiments. remarkable enhancement performance can be attributed to its optimized band structure, accelerated carrier transport separation, strong interfacial interaction, increased adsorption capacity pollutants. This study offers valuable insights designing highly efficient photocatalysts removal.

Bi₂O₂CO₃ Nanosheet Composites with Bi-Based Metal–Organic Frameworks for Photocatalytic H₂O₂ Production

ACS Applied Nano Materials, Год журнала: 2023, Номер 7(1), С. 1067 - 1077

Опубликована: Дек. 27, 2023

Heterojunction integration of inorganic semiconductors with metal–organic frameworks (MOFs) is verified to be a rational strategy achieve efficient charge separation and enhance photocatalytic performance. In this work, Bi2O2CO3/Bi-MOF heterostructures were fabricated by an in situ surface trimesic acid (H3BTC) etching method. First, Bi2O2CO3 nanosheets prepared the chemical precipitation After adding H3BTC, rod-shaped Bi-MOF was firmly anchored on because reaction Bi3+ H3BTC. As result, composites displayed enhanced H2O2 production capacities 280.5 μmol/g/h under simulated sunlight illumination, which 11.23 6.06 times higher than pure Bi-MOF, respectively. The excellent yield can attributed formation in-close contact heterostructure internal electric field between conducive inhibiting recombination photoinduced electron–hole pairs at interfaces, thus showing high This work inspire exploration construction effective inorganic/MOF hybrid for production.
