Synthesis and Electrochemical Study of Graphene-Based Nanocomposites for Hydrogen Sorption and Storage

摘要

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. However, the significant technical challenges from vehicular hydrogen storage systems such as weight, efficiency, safety and cost constraints must be properly resolved before a commercial application is possible. Compared to compressed high-pressure and liquid hydrogen storage systems, storing hydrogen in solid systems via chemisorption and physisorption is emerging as a promising approach for hydrogen storage. In this presentation, recent advances in the solid-state hydrogen storage with a high volumetric density are highlighted.
