Abstract
Nanostructured MnFe2O4 was prepared by high-energy ball milling of a stoichiometric mixture of MnO and Fe2O3 powders and characterized by XRD, TEM and TGA techniques. The ball milling process leads to strained nanocrystals with an average size of about 5Â nm, agglomerated in sizes of about 100Â nm. It was used with mechanically activated Na2CO3 to produce hydrogen from water in the temperature range 973-1073Â K. At 1023Â K the mixture shows a hydrogen production five times higher than that obtained with manganese ferrite prepared by thermally activated solid-state reaction.
