| Summary: | Title screen Magnesium-based composites with various additives have shown significant potential for hydrogen storage because of their enhanced sorption kinetics and thermodynamic stability. This study employs in situ Doppler broadening spectroscopy (DBS) to investigate defect evolution in Mg/MgH2 composites containing single-walled carbon nanotubes (SWCNTs), MIL-101(Cr) metal–organic frameworks (MOFs), nanosized nickel (nanoNi), and nanosized aluminum (nanoAl). A dedicated methodology was developed to analyze DBS spectra by evaluating the S and W parameters under controlled pressure and temperature conditions. The findings reveal the distinct impacts of each additive on defect structures, hydrogen sorption and desorption kinetics, and thermodynamic properties. This work highlights the utility of in situ DBS in elucidating the mechanisms that contribute to the improved properties of magnesium-based composites and provides key insights for the development of advanced hydrogen-storage materials AM_Agreement |
