The significant upsurge in the demand for freshwater has prompted various developments towards water sustainability. In this context, several materials have gained remarkable interest for the removal of emerging contaminants from various freshwater sources. Among the currently investigated materials for water treatment, metal organic frameworks (MOFs), a developing class of porous materials, have provided excellent platforms for the separation of several pollutants from water. The structural modularity and the striking chemical/physical properties of MOFs have provided more room for target-specific environmental applications. However, MOFs limit their practical applications in water treatment due to poor processability issues of the intrinsically fragile and powdered crystalline forms. Nevertheless, growing efforts are recognized to impart macroscopic shapability to render easy handling shapes for real-time industrial applications. Furthermore, efforts have been devoted to improve the stabilities of MOFs that are subjected to fragile collapse in aqueous environments expanding their use in water treatment. Advances made in MOF based material design have headed towards the use of MOF based aerogels/hydrogels, MOF derived carbons (MDCs), hydrophobic MOFs and magnetic framework composites (MFCs) to remediate water from contaminants and for the separation of oils from water. This review is intended to highlight some of the recent trends followed in MOF based material engineering towards effective water regeneration.
淡水需求的显著增长促使人们开发了各种水资源可持续发展技术。在这种背景下，许多材料因能够从各种淡水中去除新兴污染物而受到广泛关注。在目前用于水处理的材料中，金属有机骨架（MOFs）作为一类新兴的多孔材料，为从水中分离多种污染物提供了极好的平台。MOFs 的结构可变性和显著的物理化学性质为特定目标的环境应用提供了更多空间。然而，由于其本身脆弱的粉末状晶体形式的加工性能差，MOFs 在水处理中的实际应用受到限制。然而，人们已经认识到需要赋予其宏观形状，以便为实时工业应用提供易于处理的形状。此外，人们还致力于提高 MOFs 在水介质中因脆弱塌陷而导致的稳定性，以扩大其在水处理中的应用。MOF 基材料设计方面的进展已经朝着使用 MOF 基气凝胶/水凝胶、MOF 衍生碳（MDC）、疏水性 MOF 和磁性骨架复合材料（MFC）的方向发展，以去除水中的污染物和从水中分离油。本文旨在重点介绍 MOF 基材料工程中为实现有效水再生而采用的一些最新趋势。
