Resum
Ferrites (CoFe2O4, ZnFe2O4, MnFe2O4 and Mn0.5Zn0.5Fe2O4) nanoparticles can all significantly reduce the desorption temperature of MgH2, and CoFe2O4 shows the best catalytic performance among the four ferrites. After dehydrogenation, new by-products including Mg, Co3Fe7 and MgO phases are found for the CoFe2O4 doped samples, and Mg, Fe3Zn10, Fe and MgO phases are identified for the ZnFe2O4 doped samples. Mg, Fe, Mn and MgO phases are observed for the MnFe2O4 doped samples, while Mg, Fe3Zn10, Mn, ...
