Shaping Hierarchical Porosity Beads from Metal-Organic Framework Powders Using Freeze Spherification.

ABSTRACT: Microporous powdered Metal-Organic Frameworks (MOFs) shaped by conventional mechanical densification methods (e.g., pelletization, granulation) present internal diffusion limitations and pressure drops that limit their technological leap to industrial applications. Therefore, the ongoing search for novel shaping methods that could manufacture controlled hierarchical porous structures with enhanced diffusion, high surface area, crystallinity, and mechanical robustness is needed. In this work, a freeze spherification method is developed to shape MOF-808 powder into spherical beads with hierarchical micro/macro porosity. The optimum spherical bead composition, in terms of suspension solids loading (10, 20, or 30 vol %) and hydroxypropyl methylcellulose (HPMC) binder content (30, 25, and 20 wt
