Mg-based alloys containing MgH2 have attracted attention as hydrogen storage materials because of their thermodynamic stability and high gravimetric hydrogen density. However, there is a need to lower the temperature and increase the rate of hydrogen release and absorption for practical use. A method to prevent the aggregation of catalyst and MgH2 by treating MgH2 with fine particles and supporting them on a two-dimensional material together with a catalyst has been widely used.
Here, we report the details of the results, including the measurement of thermodynamic parameters, showing that MgH2 supported on Ni/HB nanocomposites lowers the hydrogen desorption temperature.
