Abstract

Residue organic matter such as antibiotics and dyes are left in wastewater that are difficult to remove. Herein, we reported a bismuth oxyiodide (Bi5O7I)/zeolite imidazolate framework-8 (ZIF-8) catalyst with an S-scheme heterojunction for the degradation of tetracycline (TC) using an in-situ growth strategy. The degradation process of TC is divided into two parts: adsorption and photocatalysis. Under dark reaction conditions, the Bi5O7I/ZIF-8 composites have an eminent adsorption effect on TC. When exposed to visible light, the resulting Bi5O7I/ZIF-8 composites revealed an outstanding photocatalytic activity and high stability toward TC degradation. Experiments utilizing active species trapping showed that O2 is essential to the photocatalytic process and the efficacy of the process is further improved by the addition of h+ and •OH. Likewise, these catalysts catalyzed the degradation of 84.6% of TC, and the Bi5O7I/ZIF-8 also exhibited high degradation stability after 4-cycle trial. This work optimizes the degradation performance of antibiotic residues by presenting a practical and doable approach for creating green semiconductor heterojunctions.

期刊介绍: Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
