Over the past decade, metal–organic frameworks (MOFs) have received tremendous interest in a wide variety of fields, particularly in water purification, thanks to their large surface area, adjustable topologies and high physicochemical tunability. Herein, we present an in-depth overview of MOFs materials currently available in the heterogeneous advanced oxidation processes (AOPs) for water treatment, via radical (including OH, SO, O, etc.) and/or nonradical (O, for example) mediated oxidation. The emphasis is made on the recent advance of diverse MOFs, as effective peroxide activators to generate reactive oxygen species (ROS) for organic contaminant removal in water. The further enhancements in MOFs activated peroxide processes with the photo-, electro-, and ultrasonic-assisted strategies are summarized based on the state-of-the-art development in this field. The detailed discussions have also focused on the specific behaviors, modulation strategies, role of reactive sites and mechanism of ROS formation in these MOFs activated peroxide systems. In the end, the challenge of large-scale synthesis and industrial application of MOFs towards peroxide activation is proposed, which implies great application potential of MOFs-based materials for environmental remediation.
