Hydrogen is a viable alternative to fossil fuels due to being a renewable and clean energetic vector. However, for its widespread use, it is required the development of a safe and efficient storage system. Many researchers have been studying hydrogen storage in metal hydrides, carbon nanotubes, metal-organic frameworks, among others, however, they are not yet technologically and commercially feasible. An alternative is to formulate nanocomposites with a synergistic combination of properties of a polymeric matrix and nanoparticles that can store hydrogen, in order to decrease the desorption temperature and the density of the system. This project's objective is to develop polymer nanocomposites (PEI and PEEK) by the addition of different particles with the ability to store hydrogen (Mg-Ti-Fe alloys and carbon nanotubes). For this, it will be used preparation routes based on melt and solution mixing to determine the most appropriate to provide greater particle dispersion and that have the capacity to store a significant amount of hydrogen at moderate temperatures. The samples hydrogen sorption/desorption kinetics will be evaluated in a Sievert-type volumetric apparatus and the dehydrogenation behavior in a differential scanning calorimeter (DSC) coupled with a mass spectrometer. Furthermore, the morphologies will be analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Additional characterization techniques will be used, as infrared spectroscopy (FTIR) and x-ray diffraction (XRD) analyses.
