摘要	In this study, activated carbon (AC) was added to the 2LiBH(4)-MgH2 composite and examined with respect to its effect on the hydrogen storage properties of the system. Our study found that AC is an effective additive for promoting the reversible dehydrogenation of the 2LiBH(4)-MgH2 composite. A series of control experiments were carried out to optimize the sample preparation method, milling time and addition amount of AC. In comparison with the neat LiBH4-MgH2 system, the LiBH4-MgH2 AC composite prepared under optimized conditions exhibits enhanced dehydrogenation kinetics, improved cyclic stability and particularly, eliminated incubation period between the two dehydrogenation stages. A combination of phase/microstructure/chemical state analyses has been conducted to gain insight into the promoting effect of AC on the reversible dehydrogenation of the 2LiBH(4)-MgH2 system. Our study found that AC exerts its promoting effect via tailoring nanophase structure of the 2LiBH(4)-MgH2 composite. Copyright (C) 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
