Fabrication of Ni-MOF74 derived Ni-carbon material for the highly efficient H2 gas adsorption at mild operating condition

This study fabricates nickel nanoparticle-carbon hybrid (Ni-MOF74) composite via solvothermal technique, and carbonized at different temperature under inert atmosphere, which was then used for the hydrogen storage. Morphology, crystallinity, electronic distribution and other surface properties of the synthesized material were extensively checked via different analytical techniques. Results showed that the Ni-MOF74 sample carbonized at 500 degrees C displays an improved hydrogen storage capacity of similar to 400% compared to the parent Ni-MOF74 material (0.088 vs 0.002 wt %), at 298 K and 1 atm. We believe that these Ni-carbon hybrid materials hold promising results for hydrogen storage as they show potential for storage at room temperature, and it is believed to be cost effective compared to traditionally used hydrogen spillover catalysts.
