Mingjie Cai et al.

Summary: The artificial S-scheme photocatalysis system, mimicking natural photosynthesis, has shown excellent potential for the photocatalytic degradation of pharmaceuticals and personal care products (PPCPs). In this study, Cd0.5Zn0.5S/Bi2MoO6 S-scheme heterostructures were fabricated and showed significantly improved degradation efficiency of enrofloxacin compared to Cd0.5Zn0.5S and Bi2MoO6 alone. The integration of Cd0.5Zn0.5S with Bi2MoO6 resulted in effective spatial photo-carrier dissolution and optimized photo-redox capacity, leading to enhanced photocatalytic performance and stability. The study also revealed the toxicological analysis of intermediates and showcased the potential of the system for PPPCs degradation in authentic water systems.

A novel organic/inorganic S-scheme heterostructure of TCPP/Bi12O17Cl2 for boosting photodegradation of tetracycline hydrochloride: Kinetic, degradation mechanism, and toxic assessment

Chunchun Wang et al.

Summary: This study presents a visible-light-driven organic-inorganic S-scheme heterostructure photocatalyst with excellent performance in removing antibiotics from wastewater. By anchoring TCPP on the surface of Bi12O17Cl2, the S-scheme junction between TCPP and Bi12O17Cl2 was created, enhancing the visible-light response and accelerating the disintegration and conservation of photo-carriers. The resulting TCPP/Bi12O17Cl2 showed significantly improved photocatalytic activity and stability compared to Bi12O17Cl2. Through scavenging tests, LC-MS analysis, and toxicity calculation, the reactive radicals, degradation pathway, and eco-toxicity were elucidated. This research demonstrates the potential practicality of porphyrin-based S-scheme heterojunction photocatalysts for efficient antibiotic removal.

S-scheme MIL-101(Fe) octahedrons modified Bi2WO6 microspheres for photocatalytic decontamination of Cr(VI) and tetracycline hydrochloride: Synergistic insights, reaction pathways, and toxicity analysis

Shijie Li et al.

Summary: Solar-driven elimination of refractory contaminants is an ideal approach for environmental remediation. However, the photocatalytic performance of photocatalysts is limited by insufficient reactive sites and fast recombination of electrons and holes. In this study, a novel metal-organic framework-based heterostructure of MIL-101(Fe)/Bi2WO6 was synthesized, which exhibited significantly enhanced photoactivity for Cr(VI) reduction and tetracycline hydrochloride oxidation compared to individual Bi2WO6 and MIL-101(Fe). The improved catalytic performance can be attributed to the enlarged surface area and pollutant adsorption facilitated by MIL-101(Fe), as well as the efficient photo-carrier transport mechanism supported by oxygen vacancies.

Linker regulation of iron-based MOFs for highly effective Fenton-like degradation of refractory organic contaminants

Junying Chen et al.

Summary: Iron-based MOFs with tunable structure and large surface area have been used in heterogeneous Fenton-like reactions for the degradation of new pollutants. This study investigates how the linker substituents of MIL-101 with MTN-typed topology influence the catalytic efficiency. The results show that the substituents affect crystal morphology and the MIL-101-NH2 exhibits significantly faster antibiotics removal compared to MIL-101-H due to the change in active surface.

Ta3N5/CdS Core-Shell S-scheme Heterojunction Nanofibers for Efficient Photocatalytic Removal of Antibiotic Tetracycline and Cr(VI): Performance and Mechanism Insights

Shijie Li et al.

Summary: Ta3N5/CdS core-shell S-scheme heterojunction nanofibers were prepared by growing CdS nanodots on Ta3N5 nanofibers via a wet-chemical method. These nanofibers exhibit excellent photocatalytic degradation and mineralization performance for tetracycline, as well as efficient photocatalytic reduction performance for Cr(VI). The formation of a favorable core-shell fiber-shaped S-scheme heterostructure with tightly contacted interface and maximum interface contact area ensures effective photo-carrier disintegration and optimal photo-redox capacity, leading to superior photo-redox ability. Furthermore, critical environmental factors and the degradation products of tetracycline were evaluated, and the decrease in eco-toxicity of TC intermediates was confirmed.
