Mg/transition-metal nanomaterials for efficient hydrogen storageMagnesium metal is a prominent element for solid-state hydrogen storage due to its large abundance in earth's crust and its high weight and volumetric hydrogen uptakes. However, hydrogen sorption suffers from sluggish kinetics and the formed hydride is too stable for applications working under ambient conditions. The former issue can be solved by developing composites combining two hydrides, MgH2 and TiH2 at the nanoscale. These materials are synthesized by mechanical milling under reactive atmosphere. By this technique, the formation of nanocomposites and their hydrogenation can be obtained in a single-step. Moreover, these materials can be produced at large scale for application purposes. The work focused on three topics: i) the optimization of the TiH2 content in the (1-y) MgH2+yTiH2 system. This was accomplished by optimizing the titanium content (0.0125≤y≤0.3 mole), while keeping good kinetics, hydrogen reversibility and cycle-life. The data show that y=0.025 is the best compromise to fulfill the most practical properties; ii) the extension to other transition metals for the system 0.95MgH2+0.05TMHx (TM: Sc, Y, Ti, Zr, V and Nb), evaluating the contribution of each additive to kinetics, hydrogen reversibility and cycle-life; iii) the conception of an automatic cycling device able to carry out hundreds of sorption cycles whit the aim of measuring the cycle-life of metal hydrides. The work was done using manifold experimental methods. For synthesis, reactive ball milling under hydrogen atmosphere was primarily used. The crystal structure and the chemical composition of nanomaterials was determined from X-ray diffraction (XRD) analysis. Particle size and morphology were obtained by Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDS). Thermodynamic, kinetic and cycling properties toward hydrogen sorption were determined by the Sieverts method.

Nanoscale metallic and ceramic materials, also called nanomaterials, have held enormous attraction for researchers over the past few years. They demonstrate novel properties compared with conventional (microcrystalline) materials owing to their nanoscale features. Recently, mechanical alloying and powder metallurgy processes for the fabrication of metal–ceramic/alloy–ceramic nanocomposites with a unique microstructure have been developed. This book focuses on the fabrication of nanostructured hydrogen storage materials and their nanocomposites. The potential application of the research presented in the book fits well into the EU Framework Programme for Research and Innovation Horizon 2020, where one of the societal challenges is secure, clean, and efficient energy. Wherever possible, the authors have illustrated the subject by their own results. The goal of the book is to provide comprehensive knowledge about materials for energy applications to graduate students and researchers in chemistry, chemical engineering, and materials science.

With impending serious concerns associated with climate change and the depletion of fossil fuels, an envisaged hydrogen economy remains a viable alternative for addressing future energy issues. Research into solid-state hydrogen storage has expanded significantly, with the potential to fulfill the targets established by the United States Department of Energy. The capacity for solid-state hydrogen storage of uniformly dispersed palladium (Pd) nanoparticles on boron-doped reduced graphene oxide (B-rGO) nanocomposites was measured using several electrochemical methods and other complementary techniques. The impacts of Pd nanoparticle decoration and boron substitution within the graphene composites on electrochemical performance for hydrogen storage were comparatively investigated. The cyclic voltammetry of the Pd-B-rGO nanocomposites exhibited a notable improvement in hydrogen sorption-desorption behaviors in contrast to the undoped Pd-rGO. The developed nanomaterials demonstrated enhanced performance for the electrochemical storage of hydrogen with a discharge capacity of 88 mAh g-1, which was approximately three-fold higher than Pd-rGO electrode.
