Metal-organic frameworks (MOFs) are typically synthesized in the form of crystalline powders, which possess intrinsic fragility and rigidity. These characteristics limit the industrial applicability of MOFs due to several technical challenges associated with powder forms, such as mass transfer limitations, handling difficulties, and strong pressure drops in packed beds. Recently, MOF-based aerogels have attracted wide attention because of their favorable properties, including excellent structural integrity, flexibility, and chemical stability, all of which can address the aforementioned issues. In this work, ZIF-8 nanoparticles were incorporated into silk aerogels. The large specific surface area and abundant polar groups of silk fibroin aerogels provide numerous reaction sites, allowing for strong binding interactions that facilitate the nucleation, growth, and adhesion of crystalline MOF particles. The structures and properties of the ZIF-8/silk aerogels were characterized accordingly.
