Progress in metal-organic frameworks (MOFs) as multifunctional material: Design, synthesis and anticorrosion performance techniques

In the past few years, researchers have emphasized the development of metal-organic frameworks (MOFs), which are made up of metallic ions and organic compounds as ligands. MOFs have an extensive list of potential applications as corrosion-inhibiting nanomaterials due to inherent notable characteristics, which include an enormous effective area, pore size manipulation, changeable behavior and molecular framework, and a wide range of potentially active domains. The current review focuses on the latest research on the utilization of metal-organic frameworks as anti-corrosive material. Herein, this review focuses on the latest research progress of MOF-based corrosion protection materials and reviews their anticorrosion performance, including the commonly concerned synthesis approaches of MOFs for corrosion protection with their respective advantages and shortcomings, the different anticorrosion applications, latest techniques used for screening MOF corrosion inhibition performance and the presented challenges that need to be conquered in practical applications. Meanwhile, we explained the corrosion protection mechanisms of MOFs when serve as inhibitors, nano-containers, and surface protecting coatings. At the end of this review, the future outlooks of MOFs for corrosion protection is provided, we hope this review will illuminate the achievement of high performed anticorrosion MOFs and offer new ideas for the development of MOF-based materials for future corrosion protection application.
