| 摘要: | 水体中抗生素会影响微生物群落结构和功能, 导致生态失衡; 同时, 抗生素会通过食物链的富集和传递进一步污染水质, 对生态环境和人类健康造成持续性危害. 光催化技术因其高效且环保的特性成为众多抗生素去除技术中的重点研究对象. 虽然半导体是光催化技术的核心材料之一, 但其自身限制导致工作效率不高. 生物炭(BC)作为碳家族成员之一有着众多优良特性, 将生物炭与半导体复合制备的生物炭基光催化剂(BSPs)综合了两者的优越性能, 有着广阔的应用前景. 本文通过文献查阅, 系统分析了BSPs的研究进展, 涵盖BSPs的制备和改性方式, 以及去除抗生素的原理和各种影响因素, 并阐明其高导电性、高比表面积、强氧化性、稳定性和可回收性等特点, 说明BSPs能够处理各种介质中存在的多种污染物. 此外, 对BSPs的局限性进行了分析, 对未来研究方向提出了建议. |
| Abstract: | The structure and operation of the microbial community can be altered by antibiotics in water, which can upset the ecological balance. Additionally, as antibiotics are enhanced and sent down the food chain, the quality of the water will continue to be declining, threatening both human health and the biological environment. Due to its great effectiveness and environmental protection, photocatalytic technology has emerged as a prominent research topic in various antibiotic elimination methods. Despite being one of the essential components of photocatalytic technology, semiconductor has a low work efficiency due to its inherent constraints. Biochar (BC), as a member of the carbon family, possesses several fantastic qualities. The best qualities of both are combined in biochar supported photocatalysts (BSPs), which offer a wide range of potential applications. In this paper, the research progress of BSPs is analyzed in detail through the analysis of the literature, including the methods for BSPs preparation and modification, the theory of antibiotic removal, and various influencing factors. The characteristics of high conductivity, high specific surface area, strong oxidation, stability, and recyclability are also clarified, indicating that BSPs can deal with various pollutants in various media. The limitations of BSPs are also examined in this work, and recommendations for future research paths are made. |
