摘要
The hydrogen storage and hydrogen generation of CaMg2 and CaMg1.9Ni0.1 alloys were investigated by X-ray diffraction (XRD) and pressure-composition-isotherm (PCI) measurements. The results confirmed that the CaMg2 alloy cannot absorb hydrogen at room temperature. While the addition of Ni to the CaMg2-based alloys resulted in room-temperature hydrogen absorption without an activation process, and a maximum hydrogen-absorption capacity of 5.65 wt%. The hydrolysis performance of hydrogenated CaMg2 and hydrogenated CaMg1.9Ni0.1 (abbreviated as H-CaMg2 and H-CaMg1.9Ni0.1 hereafter) was also evaluated. The hydrolysis reaction of H-CaMg2 occurred rapidly in water and resulted in a hydrogen yield of 800 mL/g. Furthermore, the hydrolysis properties of H-CaMg1.9Ni0.1 were significantly enhanced with the addition of Ni, as evidenced by a hydrogen yield of 1053 mL/g in 12 min, this yield is 94.7% of the theoretical hydrogen yield of H-CaMg1.9Ni0.1.
