| Outline of Final Research Achievements |
Developing high-capacity, low-energy hydrogen storage remains challenging, hindering its widespread adoption as a green energy solution. Despite recent advancements in nanomaterials design, fundamental hurdles persist due to an incomplete understanding of hydrogen dynamics, notably the overlooked role of quantum effects. This study investigates quantum effects on hydrogen storage within nanostructures, aiming to design effective hydrogen storage nanomaterials by optimizing adsorption and desorption dynamics. Pd-functionalized graphene and graphitic carbon nitride (g-C3N4) emerge as promising candidates for hydrogen storage. Furthermore, we uncover the significant influence of hydrogen's vibrational and rotational states on its adsorption and desorption kinetics. These findings deepen our understanding of hydrogen molecule dynamics and offer insights for enhancing nanostructured materials design, extending beyond hydrogen storage to applications like catalysis.
