Metal organic frameworks (MOFs) are porous structures, which connect inorganic units (metal ions or clusters, also known as secondary building units, SBU) and organic linkers via strong bonds[1]. These materials have had an emerging interest in the last decades due to their outstanding characteristics, which are high surface area, pore tunability and structural diversity, among others[2]. All these, make MOFs very versatile materials for a wide range of applications such as gas storage and separation, environmental remediation or biomedicine[3], as they can be tune according to the specifications required by each application.
Our group works on the formation of hierarchical framework materials (HFM). The main aim is to connect nanoparticles covalently in order to have a synergistic effect of the single nanoparticles; that is to say, to proof if the hierarchical material we would obtain after the combination of different units would outperform single nanoparticle properties. Despite many strategies have been developed, it is still challenging for scientists to reach the hierarchical complexity and advanced functions of even the most simple systems found in nature. These materials can contain hierarchical architecture, porosity or composition and understanding how hierarchy affects properties of bulk materials and how to control it is of vital importance[4].
For that, optimization of the synthetic protocols is going to be carefully done taking into account parameters like the synthetic method (microwave, oven), temperature, time and solvent, among others. For material characterization, powder X ray diffraction (PXRD), scanning electron microscopy (SEM), dynamic light scattering and thermogravimetric analysis (TGA) are going to be used in order to investigate structural aspects, size, morphology and chemical composition. Finally, the aim would be to connect nanoparticles into HFMs.
