3D printing of cellulose/leaf-like zeolitic imidazolate frameworks (CelloZIF-L) for adsorption of carbon dioxide (CO₂) and heavy metal ions

Abstract

Metal–organic frameworks (MOFs) have advanced several technologies.

Advanced Multifunctional Materials (2023)

“…3D CelloZIF-L exhibited adsorption capacities of 0.64-1.15 mmol/g for CO2 gases at 1 bar (0 °C). They showed adsorption capacities of 389.8-554.8 mg/g for Cu 2+ ions with a selectivity of 86.8% toward Fe 3+ ions [157]. A filter paper containing cellulose and ZIF-8 were reported [158,159].…”

“…The materials were used for the adsorption of carbon dioxide (CO2) and heavy metals offering capacities of 0.64-1.15 mmol/g (at 1 bar, 0 °C) and 554.8±15 mg/g, respectively. The adsorbent exhibited selectivity toward Fe 3+ , Al 3+ , Co 2+ , Cu 2+ , Na + , and Ca 2+ of 86.8%, 6.7%, 2.4%, 0.93%, 0.61%, and 0.19%, respectively [157]. Cellulose enabled also the processing of ZIF materials into filter paper [158,159] and foams [160].…”

“…Three-dimensional (3D) printing can be used to proceed MOF materials such as leaf-like zeolitic imidazolate frameworks (ZIF-L) into 3D objects with custom porosity and dimension (Figure 4) [157]. Direct ink writing (DIW) or robocasting was used to proceed with the materials.…”

An introductory review on advanced multifunctional materials

“…The materials were used for the adsorption of carbon dioxide (CO 2 ) and heavy metals offering capacities of 0.64–1.15 mmol/g (at 1 bar, 0 °C) and 554.8 ± 15 mg/g, respectively. The adsorbent exhibited selectivity toward Fe 3+ , Al 3+ , Co 2+ , Cu 2+ , Na + , and Ca 2+ of 86.8%, 6.7%, 2.4%, 0.93%, 0.61%, and 0.19%, respectively [ 286 ]. Cellulose enabled also the processing of ZIF materials into filter paper [ 287 , 288 ] and foams [ 289 ].…”

“…Cellulose-MOFs (denoted as CelloMOFs) materials have advanced several applications, including air and water remediations. [39][40][41][42] They can be used as a membrane, filters, 3D objects, and thin films. [39][40][41]43] CelloMOFs materials are promising for VOCs removal and sensing.…”
