Abstract

In this paper, First-principles calculation were used to investigate the effect of Fe substituted Co-free AB3-type hydrogen storage alloys. (La3Mg6Ni27)1/3 alloy (Hex structure) and (La3Mg6Ni26Fe1)1/3 alloy's crystal structures were build by Material studio software, Bond structure and DOS results were calculated. To compare with the calculated results, (La3Mg6Ni27)1/3 alloy and (La3Mg6Ni26Fe1)1/3 alloy were synthesized by vacuum melting method. The effect of Fe on such alloys are discussed according to calculate results and experiment results, as a first-principle investigation.
