摘要
质量轻、储量大、清洁的氢是未来一种比较理想的能源载体.而氢的安全、高效存储是实现氢应用的关键问题之一.作为一种储氢材料的储氢合金一直是储氢研究的热点之一.其中,A2B型Ti2Ni基储氢合金具有较大的理论储氢容量(约500 mAh/g),受到广泛的关注.介绍了晶态Ti2Ni合金的结构特性,概述了Ti2Ni基储氢合金的研究进展,并提出了相关研究中存在的问题及今后发展的研究方向.
Hydrogen was an ideal energy carrier because it is lightweight,abundant and clean.One of the key points for achieving hydrogen application was an effective and safe hydrogen storage.Hydrogen storage alloy,as a hydrogen storage material,had been attracting much attention with particular in A2B-type Ti2Ni-based ones.They had a high theoretical storage capacity of about 500 mAh/g.This review introduced the structure of crystalline Ti2Ni alloy,the research progress of Ti2Ni-based hydrogen storage alloy,and the probable future work and some related problems.
