Doping with Metal and Compound to Improve the Properties of Hydrogen Storage of MgH_2

Recently,magnesium hydride MgH2 is one of the attractive hydrogen storage materials because it reaches a high hydrogen capacity.However,the reaction kinetics is too slow and needs high temperature for progressing hydrogen absorption and desorption reactions,which hinders the process of practical applications and it is necessary to improve the hydrogen storage propesties.Most used or under research methods(doping with metal and compound)which can improve the hydrogen storage of magnesium hydride are reviewed,in particular to elements substitution,addition of transition metal oxides or fluorine and so on.The advantages and disadvantages of vaious methods which can improve the hydrogen storage of magnesium hydride are compared.The trend of the methods of improving is also introduced.
