Porous materials such as Metal-organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs) are hybrid porous materials consisting of metal ions connected with organic linkers . Processing MOFs using template materials gives rise to a new class of mixed materials that combines the advantages of both components . In recent years, hybridizing biopolymers such as cellulose with MOFs has resulted in the development of cellulose-MOF functional materials, which opens up vast new advantages in terms of high performance, good processability, and good sustainability . Cellulose-MOFs have thereby several advanced applications, for instance, drug delivery , carbon dioxide (CO2) adsorption , water remediation , thermal insulation, and fire retardancy . Combining MOFs with cellulose offers significant processing flexibility, which is inherently limited for MOFs, using methods such as three-dimensional (3D) printing , freeze-drying , and sol-gel . These methods can, among others, engineer cellulose-MOFs into scaffolds , elastic aerogels , foams ,
