Abstract

Hydrogen is now being used as a renewable clean energy carrier. One of the main issues with the application of hydrogen energy is a shortage of security and efficient hydrogen storage technology. TiMn-based alloys are considered promising hydrogen storage materials, but their comprehensive hydrogen storage properties and cyclic stable performance limit their further practical application. The hydrogen storage properties of alloys can be enhanced by substituting transition metal elements. Therefore, the comprehensive hydrogen storage performance of the Ti_0·9Zr_0·1Mn_0·95Cr_0·7V_0.2M_0.15 (M = Fe, Co, Ni, Cu, Mo) alloys was systematically investigated according to the Mn element on the B side is partially replaced by variety of transition metal elements. The M = Ni alloy, which showed the highest hydrogen storage capacity among the group of alloys, was used to explore cycle stability. The plateau pressures of the series alloys decreased in order, Fe > Co > Ni > Cu > Mo. Aspects of hydrogen absorption kinetics, all of the alloys can reach full hydrogen absorption saturation within 400 s at 303 K. The Ti_0·9Zr_0·1Mn_0·95Cr_0·7V_0·2Mo_0.15 alloy possessed the fastest hydrogen absorption kinetic rate (t_0.9 = 65 s) and the smallest hysteresis factor. This suggests that the substitution of Mo elements is effective in improving the hysteresis of the Laves phase alloys. Among the series of alloys, the M = Ni alloy exhibited the best overall hydrogen storage performance, which hydrogen storage capacity can reach 1.81 wt% and 97% of its capacity is kept after 100 cycles.

不同金属元素替代对 Ti0-9Zr0-1Mn0-95Cr0-7V0.2M0.15（M = Fe、Co、Ni、Cu、Mo）合金微观结构和综合储氢性能的影响

氢气目前正被用作一种可再生的清洁能源载体。氢能应用的主要问题之一是缺乏安全高效的储氢技术。钛锰基合金被认为是很有前途的储氢材料，但其全面的储氢特性和周期稳定的性能限制了其进一步的实际应用。通过替代过渡金属元素，可以增强合金的储氢性能。因此，根据 B 侧 Mn 元素被多种过渡金属元素部分取代的情况，系统研究了 Ti0-9Zr0-1Mn0-95Cr0-7V0.2M0.15（M = Fe、Co、Ni、Cu、Mo）合金的综合储氢性能。M = Ni 合金在这组合金中显示出最高的储氢能力，被用来研究循环稳定性。该系列合金的高原压力依次为 Fe > Co > Ni > Cu > Mo。在氢吸收动力学方面，所有合金都能在 303 K 下的 400 秒内达到完全氢吸收饱和状态。Ti0-9Zr0-1Mn0-95Cr0-7V0-2Mo0.15 合金的吸氢动力学速率最快（t0.9 = 65 秒），滞后因子最小。这表明钼元素的替代能有效改善拉维斯相合金的滞后性。在这一系列合金中，M = Ni 合金的整体储氢性能最好，储氢容量可达 1.81 wt%，100 次循环后仍能保持 97% 的储氢容量。
