Hydrogen as an energy source is quite attractive because it prevents air pollution and greenhouse emissions. However, one of the main problems with the utilization of hydrogen is its on-board storage. The purpose of this work was to develop a new hybrid material consisting of a sulfonated polyetherimide matrix with aluminum nanoparticles and faujasite type zeolite. Dilute solutions were first prepared under stirring at room temperature and the solutions were dried under vacuum. The hybrids were analyzed by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Transmission Electron Microscopy (TEM) and Hydrogen sorption measurements. The addition of aluminum decreased the glass transition temperature of the hybrids when compared to the sulfonated polymer. TEM analysis was performed to identify the morphology of the hybrid material and it was observed that simply physically mixture occurred between polymer matrix and metallic nanoparticles.
