肼常被应用于航天飞行器姿态控制,这需要肼快速分解放出高温高压气体,故要求催化剂能够快速催化分解肼释放气体;但近年来肼被用作储氢材料和还原剂等而使其应用领域被逐渐扩大,这方面则需要肼进行完全脱氢分解达到肼的最大利用率,故要求催化剂的催化分解具有选择性。因此选择性分解肼成为肼催化剂研究的重点。在简介肼主要的应用方向的基础上,归纳总结了国内外选择性分解N_2H_4的催化剂的发展历程、取得的研究成果及近年来的发展动态,并分析了催化剂选择性催化肼的机理,最后指出了目前选择性分解N_2H_4的催化剂存在的问题及未来的研究方向。

Hydrazine is often used in spacecraft attitude control, that means hydrazine needs decompose rapidly and release of high temperature and high pressure gases, requires that catalyst can catalyze the decomposition of hydrazine and release gas fast. But in recent years hydrazine has been used as a hydrogen storage material and reducing agent,and its application has been gradually expanded, this need the hydrazine decompose in the way of completely dehydrogenation in order to achieve the maximum utilization and requires the catalyst catalyze selectively. Therefore, selective decomposition of hydra...
