| Title: | Interaction between lithium amide and lithium hydride | Authors: | Chen, P. Xiong, Z. Luo, J. Lin, J. Tan, K.L. |
Issue Date: | 2-Oct-2003 | Citation: | Chen, P.,Xiong, Z.,Luo, J.,Lin, J.,Tan, K.L. (2003-10-02). Interaction between lithium amide and lithium hydride. Journal of Physical Chemistry B 107 (39) : 10967-10970. ScholarBank@NUS Repository. | Abstract: | Pure lithium amide (LiNH2) decomposes to lithium imide and ammonia at temperatures above 300°C. Lithium hydride, on the other hand, liberates hydrogen at temperatures above 550°C. By thoroughly mixing these two substances and conducting temperature-programmed desorption (TPD), we noticed that hydrogen was produced at temperatures around 150°C. Combined thermogravimetric (TG), X-ray diffraction (XRD), and infrared (IR) analysis revealed that lithium amide would react with lithium hydride and convert to hydrogen and lithium imide (or Li-rich imide). The reaction mechanism was investigated by isotopic exchange. | Source Title: | Journal of Physical Chemistry B | URI: | http://scholarbank.nus.edu.sg/handle/10635/96948 | ISSN: | 15206106 |
