|Title:||Chemical reaction of amides and hydrides||Authors:||Xiong, Z.
|Issue Date:||2005||Citation:||Xiong, Z.,Hu, J.,Wu, G.,Chen, P. (2005). Chemical reaction of amides and hydrides. ACS Division of Fuel Chemistry, Preprints 50 (2) : 501-502. ScholarBank@NUS Repository.||Abstract:||Five novel Metal-N-H systems were developed accordingly, among which three systems could release substantial amount of hydrogen (> 4.2 wt %) near ambient temperature. As the H-deficient phase of Metal-N-H was somewhat with imide-like behavior, the following equation may account for the general features of the amide-hydride reaction: M1-NH2 + M2Hn → (M1-M2-NH) + H2. M1 and M2 represented alkali and/or alkali earth metals. Structural changes before and after interaction were rather important. However, the poor crystallinity of the ball milled samples brings difficulties for the X-ray characterization. The challenges posed to the Metal-N-H system for hydrogen storage purpose were the reversibility (especially for those ambient temperature systems), capacity, and the chemical stability. This is an abstract of a paper presented at the ACS Fuel Chemistry Meeting (Washington, DC Fall 2005).||Source Title:||ACS Division of Fuel Chemistry, Preprints||URI:||http://scholarbank.nus.edu.sg/handle/10635/98652||ISSN:||05693772|
