综述了国内外对于NaAlH4体系中Ti催化剂催化机理的最新研究,阐述了目前学术界存在的对于NaAlH4体系中Ti催化剂作用机理的2种不同观点:取代机理及氧化还原机理.列举了2种机理分别对应的中间产物并进行了分析.对于Ti添加NaAlH4体系的研究提出了一些不足之处以及改进方法.

In this paper,the latest research on the catalytic mechanism of Ti in NaAlH4 system at home and abroad is introduced,and two different opinions about catalytic mechanism of Ti in NaAlH4 system are discribed:the substitution mechanism and the redox mechanism.Different intermediate products containing Ti are presented and analyzed.Shortcomings and improvements for the Ti-doped NaAlH4 system are also summarized.
