Abstract

Here we report a TiV-10 wt.% C alloy with a unique lattice and microstructure for hydrogen storage development. Different from a traditionally synthesized TiV alloy prepared by a melting method and having a body-centered cubic (BCC) structure, this TiV-C alloy synthesized by a mechanical alloying method is with a face-centered cubic (FCC) structure (space group: No. 225). The crystalline size is 60 nm. This alloy may directly absorb hydrogen near room temperature without any activation process. Mechanisms of the good kinetics from lattice and microstructure aspects were discussed. Findings reported here may indicate a new possibility in the development of future hydrogen storage materials.

摘要

在这里，我们报道了一种 TiV-10wt.%C 合金，它具有独特的晶格和微观结构，可用于储氢开发。与传统的通过熔炼方法制备的体心立方 (BCC) 结构的 TiV 合金不同，通过机械合金化方法合成的 TiV-C 合金具有面心立方 (FCC) 结构（空间群：No.225）。其晶体尺寸为 60nm。该合金无需任何活化过程即可在接近室温的条件下直接吸收氢气。从晶格和微观结构方面讨论了良好动力学的机制。这里报道的发现可能为未来储氢材料的发展提供了新的可能性。
