Polymer-stable magnesium nanocomposites prepared by laser ablation for efficient hydrogen storage

Laser ablation shows great potential as a scalable method for the production of metal hydrides due to its capability of fabricating single phase, fine nanoparticles with a maximum dispersion while being a relatively low-cost process. The encapsulation of the Mg-nanoparticles in a polymer matrix allowed to achieve a rapid uptake (<20 min at 250 °C) of hydrogen with a high capacity (6 wt. % in Mg, 5.5 wt. % overall).
