There has been renewed interest in the development of hydrogen storage technologies. While existing research in this field primarily concentrates on solid-state hydrogen storage materials utilizing metal-based inorganic compounds, this particular study sought to synthesize and conduct molecular analyses of a metal-based organic molecule for solid-state hydrogen storage. The synthesized metal-based organic molecule, methylene crosslinked 25,26,27,28-tetrahydroxycalix[4]arene resin loading metallic palladium (MC-[4]H-Pd(0)), exhibited the presence of several significant functional groups, including phenyl rings and hydroxyl groups, as indicated by the results of FT-IR spectra. The total mass of palladium metals loaded in MC-[4]H-Pd(0) was determined to be 7.61%. These outcomes provide compelling support for the continued exploration of metal-based organic molecules as potential solid-state hydrogen storage materials. © 2025 Vietnam Academy of Science and Technology and Wiley-VCH GmbH.
