Recent Progress in Metal-Organic Frameworks@Cellulose Hybrids and Their Applications

In recent years, metal-organic frameworks (MOFs) are attracting increasing attention due to their charming properties. However, the intrinsic fragility, powdered crystalline state, and poor processibility of MOFs hinder their further application. By this, the designs of MOF-based aerogels, hydrogels, membranes are effective ways to solve this problem. Graphene, silica, synthetic polymer and cellulose are the commonly used raw materials for fabricating MOF-based aerogels, hydrogels, and membranes. Among them, cellulose and its derivatives are the best candidates to support the powdered MOFs from the perspectives of economy, environmental protection and property. This review focuses on discussing the advantages of MOF@cellulose hybrids in applications such as water treatment, antibacterial, gas separation and adsorption, energy storage, drug delivery, catalysis, and other smart composites. MOF@cellulose-based aerogels, hydrogels and membranes can provide valuable guidance for investigating the practical application of MOFs in terms of processability, reusability, stability and easiness in handling.
