Structural characteristics and hydrogen storage of C24H20N4NiO2•2(C4H4NO4S)•H2O component performance determination

Hydrogen energy is seen as the energy of the future and one of the biggest problems with hydrogen energy nowadays is the storage of hydrogen. The storage of high amounts of hydrogen in small volumes is important for the widespread use of hydrogen energy. Depending on the places of use, hydrogen, gas or liquid can be stored purely in the tanks, as well as physically bonded to the surfaces and can be stored interactively or chemically. One of these methods is the storage in metal organic compounds (MOFs). In this study, the molecular structure of the "C24H20N4NiO2•2(C4H4NO4S)•H2O" compound was first elucidated by the single crystal X-ray diffraction (XRD) method. Single crystal XRD results show that the metal complex is crystallized in the triclinic system in the P-1 space group. In the second step, the hydrogen storage capacity of the complex is determined experimentally as 1.3774 mL/g and wt0.044% at 77 K and 1 bar pressure.
