| Popis: |
The promising applications of metal-organic frameworks (MOF) can be widened if these materials were additive manufactured to develop three-dimensional (3D) MOF architectures. In this work, iron-based MOF/silicon carbide (SiC) composite aqueous inks with a high solids content (64 wt%) are printed into 3D periodic lattices by a direct ink writing technique (Robocasting). MOF appear fully integrated within the cellular architectures, which display total porosities in the range of 74–78% depending on the scaffold design. The 3D MOF-Fe/SiC structures exhibit good mechanical strength (~4.6 MPa) and a semiconductor-like behaviour. The structures show a remarkable response in the hydroxylation of phenol with hydrogen peroxide, demonstrating high selectivity and yield to dihydroxybenzene species. |
