Abstract
Hydrogen energy, as a clean energy source, requires efficient storage for its widespread application, and this study focuses on optimizing the performance and application of hydrogen storage materials to enhance their energy density, cycling stability, and safety. Addressing the current issues of low energy density and slow hydrogen absorption/desorption rates in existing materials, this research combines theoretical calculations with experimental methods to modify various hydrogen storage materials. Representative me tal hydrides and organic compounds were selected as research subjects; first-principles calculations were employed to predict potential high-performance hydrogen storage materials, which were then validated through synthesis preparation, structural characterization, and performance testing. It was found that elemental doping and nanostructural design significantly improved the hydrogen storage capacity and reaction kinetics of me tal hydrides, while introducing specific functional groups enhanced the hydrogen absorption capability and thermal stability of organic compounds. An innovative aspect of this study is the proposal of a synergistic optimization strategy based on multiscale simulations and experimental feedback, achieving precise control over the performance of hydrogen storage materials. This research provides theoretical foundations and technical support for developing new efficient hydrogen storage materials, potentially accelerating the practical application of hydrogen energy technology in transportation, energy storage, and other fields, thus contributing significantly to the establishment of a sustainable energy system.
