<p>We report a solvent-free procedure for the high-yield synthesis of metal-organic frameworks of UiO-66 topology starting from a range of commercial Zr(IV) precursors and various substituted dicarboxylic linkers. The syntheses are carried out by simply grinding the reagents in the presence of a small volume of acetic acid as modulator, followed by incubation at either room temperature or 120 °C. Use of a ball mill for the grinding step is demonstrated to enable facile scale up of the synthesis. High acidity of the linker is found to be a crucial factor in affording materials of quality comparable to that of products obtained in solvo- or hydrothermal conditions.</p>

Metal-organic frameworks (MOFs) were usually synthesized in hydrothermal conditions; in this study, a more energy-saving, easier to control, and solvent-free mechanochemical method was firstly applied to synthesize MOFs with varied reactants as slow release fertilizer, and the components and structures were characterized by X-ray diffraction (XRD), Fourier transform infrared total attenuated reflectance (FTIR-ATR), and laser-induced breakdown spectroscopy (LIBS). Results showed that three MOFs (compounds I, II, and III) were obtained, the MOFs were confirmed as oxalate phosphate oxalate frameworks (OPA-MOF), and ions were adsorbed between layers that contributed to the contents, while urea molecules mainly impacted the structure. The elemental compositions significantly varied among the three compounds; compound I showed the highest content of N (4.91%), P (15.71%), and Fe (18.60%), compound III indicated the highest content of C (6.52%) and K (12.59%), while the contents of C, K, P, and Fe in compound II were in the medium range. Similar release profiles of Fe and P were found among the three MOFs, and the release rates of nutrients were demonstrated as the order of N > K > P > Fe. The compositions and release profiles demonstrated potential application of MOFs as a novel slow-release fertilizer.
