Resum
The catalytic effects of MnFe2O4 nanoparticles on the dehydrogenation properties of NaAlH4, prepared by ball milling, are investigated. The onset temperatures for NaAlH4 + 7 mol% MnFe2O4 are 95 C, 152 C and 327 C for the three dehydrogenation steps, significantly lower compared with as-received NaAlH4. The isothermal dehydriding kinetics shows that adding MnFe2O4 to NaAlH4 could significantly enhance the desorption kinetics of NaAlH4, 7 mol% MnFe2O4-doped sample also displays the well-maintained...
