Rational design of recyclable metal-organic frameworks-based materials for water purification: An opportunity for practical application.

ABSTRACT

Due to their high specific surface area (SSA), numerous active sites, and customizable pore structure, metal-organic frameworks (MOFs) have emerged as a popular topic in wastewater treatment research. Unfortunately, MOFs exist in the form of powder, which poses significant challenges such as difficult recycling and powder contamination in practical applications. Accordingly, for solid-liquid separation, the strategies of endowing magnetism and constructing appropriate device architectures are important. This review offers a detailed overview of the preparation strategies for recyclable MOFs-based magnetism and device materials and introduces the characteristics of these preparation methods through relevant instances. Besides, these two recyclable materials' applications and working mechanisms for removing pollutants from water through adsorption, advanced oxidation, and membrane separation technologies are introduced. The findings presented in this review will provide a valuable reference for the preparation of MOFs-based materials with excellent recyclability.
