LiNH complex hydrides were prepared by mechanical alloying and the effects of B and C as catalyst on hydrogen storage properties were investigated. The results show that LiNH2 and Li2NH are the main phases in Li-N-H complex hydrides and the amorphous degree of the main phases increase with B element added. Although the hydrogen storage capacity decrease with B and C element added, the effective hydrogen storage capacity increase and the kinetic properties of hydrogen absorption/desorption can be improved when the adding n(B)∶n(C)=1∶2. The hydrogen absorption/desorption temperature can be decreased effectively with adding B. The reversible hydrogen absorption/desorption capacity can also be improved with milling time prolonging.
