A review of metal-organic framework protective coatings for light metals

Abstract

Corrosion of metals is a long-standing problem in many engineering fields. Recently, microporous and nanoporous materials, MOFs (metal-organic frameworks), have attracted much attention in the field of inorganic and organic chemistry. However, there are few studies on MOFs as protective coatings. This paper reviews (i) the basic structure, synthesis methods and types of MOFs, (ii) their growth patterns, (iii) research progress and functional mechanisms of MOFs in different fields (such as corrosion resistance, antibacterial and flame retardant), (iv) computational chemistry in the research field of MOFs to provide theoretical basis for designing MOFs with the best performance, determining the best synthesis conditions and operating parameters and (v) the application prospect of MOFs in the field of corrosion, and attempts to spread the application of MOFs to other fields.

“…Notable features of MOFs include their ability to select and design suitable ligands with various types of metal knots with suitable and predictable geometry, robustness, and different coordination modes [23,24]. Furthermore, their consistent pore structure, expansive surface area (around 4000 m2/g), and adjustable composition render them highly suitable for various applications such as drug delivery, gas detection, separation processes, and heterogeneous nanocatalysis [25][26][27][28].…”

[25][26][27][28] Fe-based MOFs exhibit high porosity and surface area, which make them promising materials for applications such as gas storage and separation, catalysis, sensing, proton conduction, and drug delivery. 29 Fe-based MOFs have been widely and successfully applied as catalysts for reactions requiring acidic or redox centers.…”
