The hydrogen storage properties of MgH2 ball milled with 20wt.% Na2WO4 have been investigated. The MgH2+20wt.% Na2WO4 composite has favorable hydrogenation and dehydrogenation properties as well as low decomposition temperature. When compared with the pristine MgH2, the total hydrogen absorption capacity of MgH2+20wt.% Na2WO4 composite increased from 0.98wt.% to 2.27wt.% in 20min at 423K, and the...
