FeCrAlloy® foils are commonly used for fabricating metallic monoliths. However, their lack of specific surface area/roughness (pores) hinders catalyst adhesion during the coating process. Several pre-treatment processes have been investigated in recent years. Is it possible to exploit the high porosity of MOFs as a primer, thereby enhancing catalyst adhesion on these monoliths for the development of more stable structured catalysts?
Yes, metal-organic frameworks (MOFs) can be effectively used as primers on metallic monoliths, enhancing their functionality for applications like catalysis, gas adsorption, and sensing. MOFs increase the surface area, introduce functional groups, and improve stability. Techniques such as in situ growth, layer-by-layer assembly, and chemical vapor deposition ensure uniform and strong adhesion of MOFs to metallic surfaces. This integration leverages the high surface area and tunable porosity of MOFs, enhancing the performance and durability of metallic monoliths in various advanced technological applications. Challenges like achieving uniform coatings and ensuring scalability are areas of ongoing research.
