Photocatalytic coupling technologies have emerged as popular strategies to increase the treatment efficiency of dye-containing wastewater. Herein, Z-scheme Co3O4/BiOBr heterojunction (Z-CBH) was constructed and developed a photocatalytic peroxydisulfate (PDS) activator for degradation high-concentration Rhodamine B (RhB). Multiple testing techniques were employed confirm formation Z-CBHs. When 0.1 g·L–1 Z-CBH20 1.0 mmol·L–1 PDS added simultaneously under simulated sunlight irradiation, RhB could approach 91.3%. Its reaction rate constant (0.01231 min–1) much beyond sum those in Z-CBH20/light system (0.00436 PDS/light (0.0062 min–1). h+, •OH, •O2–, SO4•–, 1O2 detected dominant reactive species degradation. The potential mechanism oxidation proposed. possible intermediates determined by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry assisted with density functional theory Fukui theory. pathways put forward. toxicological properties its evaluated quantitative structure–activity relationship prediction. This work will not only provide reference developing persulfate activators but also gain an insight into toxicity intermediates.

Three-Dimensional Multihierarchical Hexagonal/Cubic ZnIn₂S₄ S-Scheme Heterophase Junction for Superior Photocatalysis

Inorganic Chemistry, Год журнала: 2024, Номер 63(4), С. 2157 - 2173

Опубликована: Янв. 11, 2024

It is an important strategy to design composite materials with a special microstructure and tunable electronic structure through structural compatibility. In this work, novel hexagonal/cubic ZnIn2S4 polymorphic heterophase junction three-dimensional multihierarchical successfully constructed by in situ growth of hexagonal nanosheets on the surface cubic flower-like microspheres prepared topological chemical synthesis. On one hand, architecture provides large specific area, abundant active sites, excellent light trapping capability. other construction direct S-scheme enables formation charge-transfer channel under force built-in electric field, which not only improves separation efficiency carriers but also ensures stronger reaction activity charges. The photocatalyst exhibits greatly boosted photocatalytic rhodamine B degradation, hexavalent chromium reduction, water splitting for hydrogen production, are 12.3, 6.5, 3.1 times higher than that pure 8.1, 5.1, 2.3 ZnIn2S4, respectively, demonstrating its significant potential applications energy environmental fields.
