摘要
金属氘化物作为新型绿色能源材料,储氘性能优异,在能源领域应用的重要性和广泛性日益凸显。随着社会的发展与实际应用的不断深化,金属氘化物能源材料将对国家的能源战略起到至关重要的作用。金属氘化物通常是在高温环境下直接化合进行制备,由于其表面化学性质十分活泼,在空气氛围尤其是高湿度(大于60%以上)空气气氛中极易受O_(2)、CO_(2)、H_(2)O等腐蚀,进而导致金属氘化物性能改变,严重时可能存在安全隐患,使用范围受到一定限制。目前,多种金属氘化物材料如氘化锂、氘化钛、氘化锆以及氘化铈等相继被制备出且有一定的应用。本文基于金属氘化物的分类、特性以及应用,概述了几种常见金属氘化物的制备与应用研究进展,总结了金属氘化物的研究现状与进展并提出展望,意在为金属氘化物的制备研究与应用提供借鉴。
As a new type of green energy material,metal deuteride has excellent deuterium storage performance,and its importance and widespread application in the energy field have been more and more outstanding.Under the high speed of social and practical applications'development,metal deuteride energy materials will play a more and more important role in the country's energy strategy.The metal deuterides is usually prepared by direct compounding in a high-temperature environment.It is highly susceptible to O_(2),CO_(2),H_(2)O,etc in the air atmosphere,especially the high humidity(more than 60%)air atmosphere because of the very active surface chemistry.It can cause changes in the performance of metal deuterides,which may cause safety hazards in severe cases,and the scope of use is limited.At present,a variety of metal deuteride materials such as lithium deuteride,titanium deuteride,zirconium deuteride and cerium deuteride have been prepared successively and have certain applications.This article summarizes the research progress of several common metal deuterides preparation and application according to the cha-racteristics,classification and applications of metal deuterides,summarizes the research status and progress of metal deuterides,and puts forward prospects.The purpose is to summarize data and reference for the research and application of deuterated metals.
