Solid-state hydrogen storage is one of the most promising hydrogen storage methods.Light metal hydrides such as lithium aluminum hydride (LiAlH4),sodium aluminum hydride (NaAlH4) and magnesium hydride (MgH2) have the advantages of high capacity and low cost,which are the focus of research on solid hydrogen storage materials.However,high hydrogen absorption/desorption temperatures and slow kinetic properties hinder their practical application.Doping catalysts can effectively reduce the kinetic energy barriers of light metal hydrides such as LiAlH4,NaAlH4 and MgH2,which is an effective way to improve the hydrogen absorption/desorption performance.This paper reviewed the research progress in the basic properties,hydrogen storage principles,doping modification,and catalytic mechanisms of light metal hydrides LiAlH4,NaAlH4,and MgH2,and also presented an outlook on the future research directions of light metal hydrides.
