摘要
随着水体污染问题的日益严重,特别是新污染的不断出现,传统污水处理方法已难以满足高效、绿色的处理需求。金属有机骨架(MOFs)因其具有可调控的孔径、高孔隙率、易改性等优点,在高级氧化处理废水领域展现出巨大潜力。然而,MOFs多为粉末状,参与反应后不易回收。因此,固定化MOF材料成为其在水处理领域广泛应用的研究热点。本文综述了当前固定化MOF材料的主要方法,包括原位生长法、二次生长法、电化学生长法、逐层沉积法等,并探讨了固定化MOFs材料在水处理领域的吸附、高级氧化技术的应用及作用机制。最后,展望了未来MOFs材料在水处理领域的发展方向。
With the escalating issue of water pollution,especially given the relentless emergence of new pollutants,traditional wastewater treatment methods are proving insufficient to meet the growing need for efficient and eco-friendly solutions.Metal-organic frameworks(MOFs)stand out due to their adjustable pore sizes,high porosity,and ease of modification,showcasing considerable potential in advanced oxidation processes for wastewater treatment.However,a significant challenge lies in the fact that most MOFs are in powder form,complicating their recovery after use.As a result,immobilizing MOF materials has become a focal point of research aimed at broadening their application in water treatment.This article surveys the current leading methods for immobilizing MOF materials,encompassing in-situ growth,secondary growth,electrochemical deposition,and layer-bylayer deposition.Furthermore,it delves into the applications and underlying mechanisms of immobilized MOFs in water treatment,particularly emphasizing their roles in adsorption,catalysis,and advanced oxidation processes.Finally,the article anticipates the future trajectory of MOF materials in the realm of water treatment.
