CABANAS-MORENO, J.G.  e  PALACIOS-LAZCANO, A.F.. Comentarios al artículo "Hydrogen desorption process in Mg₂Ni hydrides", de J.L. Iturbe-García, B.E. López-Muñoz, R. Basurto, y S. Millán, Rev. Mex. Fís. 52 (4) 365. Rev. mex. fis. [online]. 2007, vol.53, n.6, pp.495-495. ISSN 0035-001X.

A mistaken interpretation of the results of dehydriding experiments performed on Mg2Ni powders is noticed, as the authors report hydrogen release in quantities exceeding the maximum theoretical storage capacity of this compound. In addition, it is pointed out that the authors fail to acknowledge the work of A.F. Palacios-Lazcano in the preparation of the materials used in their study, as well as in the results of characterization included in the said article.

Palavras-chave : Hydrogen storage materials; nanocrystalline magnesium alloys; metal hydrides.
