“…C14 secondary phase. In our previous work [10], we have found that Ce addition was useful for suppressing the formation of secondary phases and increasing the maximum and reversible hydrogenation capacities of Ti-Cr-V BCC alloys. In this paper, the effect of Ce addition on the improvement of the hydrogen storage properties of the (Ti 0.267 Cr 0.333 V 0.40 ) 93 Fe 7 alloy is investigated.…”

“…The alloys consist of two phases identified by EDS, a light spherical CeO 2 phase is observed in the gray Laves phase matrix, and this result is coincident with the one measured by XRD analysis. Since Ce element has strong affinity with oxygen, it reacted with oxygen to form CeO 2 phase and reduces oxygen concentration dissolved in the matrix [14]. Fig.…”

The effect of Ti content on the hydrogen storage properties of Zr 1−x Ti x Mn 2 Ce 0.015 (x = 0, 0.2, 0.3, 0.5) alloys was studied by X-ray diffraction, scanning electron microscopy and pressure-composition (p-c) isotherm measurement. All of the alloys mainly consist of C14-type Laves and CeO 2 phases. As the Ti content increases, the lattice parameters of the Laves phase decrease and the unit cell shrinks anisotropically, the total hydrogen absorption capacity decreases but the reversible hydrogen desorption capacity of the alloys increases, and the equilibrium pressure of the alloys increases but the plateau becomes sloping. The changes of hydrogen storage properties of Zr 1−x Ti x Mn 2 Ce 0.015 alloys are related to the differences in both atomic radius and hydrogen affinity between Ti and Zr elements.

“…In our previous work, we found that Ce can suppress the formation of the second phase, favor the chemical homogeneity and, therefore, improve the hydrogen storage properties of the alloy [7] . The effect of Si on the Ce-added Ti-V based alloy has not been reported.…”

In this paper, the effects of Si and Ce on the microstructure and hydrogen storage property of Ti 26.5 Cr 20 V 45 Fe 8.5 Ce 0.5 alloy were studied, respectively. First of all, effects of Si on the microstructure and hydrogen storage properties of Ti 26.5 Cr 20 (V 45 Fe 8.5 ) 1−x Si x Ce 0.5 (x = 0, 0.5, 1.0, 1.5 and 2.0 at%) alloys were studied by X-ray diffraction, scanning electron microscopy and P-C isotherm measurements. As the Si addition increases, the hydrogen absorption capacities of alloys decrease but the equilibrium pressure increases, due to the formation of Laves phase. Secondly, the effect of Ce on Ti 26.5 Cr 20 (V 45 Fe 8.5 ) 0.98 Si 2 alloy was studied. It was found that Ce addition is an effective way to eliminate the effect of Si on the hydrogen storage properties of the alloy.hydrogen storage materials, Ti-V based alloy, Laves phase
