Direct ink writing of catalytically active UiO-66 polymer composites.

Metal-organic frameworks (MOFs) hold significant potential for use in gas storage, sensing and catalysis. To uncover this potential, MOF processing must develop in line with MOF materials. Here, direct ink writing-based 3D printing of UiO-66 MOF composites and their thermal treatment give mechanically stable yet highly porous composites effective for the catalytic breakdown of methyl-paraoxon, a simulant of highly toxic organophosphate nerve agents.

Magnetic Control of MOF Crystal Orientation and Alignment.

Most metal-organic frameworks (MOFs) possess anisotropic properties, the full exploitation of which necessitates a general strategy for the controllable orientation of such MOF crystals. Current methods largely rely upon layer-by-layer MOF epitaxy or tuning of MOF crystal growth on appropriate substrates, yielding MOFs with fixed crystal orientations. Here, the dynamic magnetic alignment of different MOF crystals (NH -MIL-53(Al) and NU-1000) is shown.
