| dc.description.abstractEn | The H sorption properties of mixtures Mg + WO<sub>3</sub> (having various structures) and Mg + H<sub>0.23</sub>WO<sub>3</sub> are reported. First, the higher conversion of Mg into MgH<sub>2</sub> during reactive mechanical grinding (under 1.1 MPa of H<sub>2</sub>) for higher WO<sub>3</sub> content is due to the improvement of the milling efficiency. Then, it is shown that the hydrogen absorption properties are almost independent of the crystal structure of the catalyst and that only the particles' size and the specific surface play a major role. Finally, for the desorption process, it appears that the chemical composition and structure of the catalyst, together with the particle size and specific surface have an effect. | |
