HYDROGENATION PROPERTIES OF Mg-Al-Ti-Zr-C COMPOSITE

Popis výsledku v původním jazyce

The improvement of hydrogen storage properties of ball-milled Mg-Al-Ti-Zr-C composite was studied in thisnpaper. It has been previously shown, that the addition of Ti, Zr, Al and C improves storage properties of Mg.nThis beneficial effect of additives upon hydrogen storage properties can be explained by catalysis by thennanoparticles rich in Ti, Zr or Al located on the surface of Mg grains. They provide effective pathways for thenhydrogen diffusion into the MgH2. The morphological and microstructural characteristics were investigated bynscanning electron microscope Tescan Lyra 3 and by X-ray diffraction. The hydrogen sorption was measurednby Sieverts method using Setaram PCT-Pro device.nStudied experimental composite absorbed 4.2 wt.% H 2 at 573 K and 3 wt.% H 2 at 523K within 10 min. Thenhydrogen storage capacity of the composite was about 4.6% wt.% H 2 and 4.2% wt.% H 2 at 573K and 523K,nrespectively.
