MgH2 is a very hopeful material for application as hydrogen storage in the solid form. This due to its reversibility and ability store large amounts of hydrogen, which 7.6 wt%. However, this still has weaknesses, namely high operating temperature slow kinetic reactions. Various attempts have been made overcome weakness, including downsizing adding catalyst. In study, double catalyst was used, n...
