|Title:||Improvement of hydrogen storage properties of the Li-Mg-N-H system by addition of LiBH4||Authors:||Hu, J.
|Issue Date:||8-Jul-2008||Citation:||Hu, J., Liu, Y., Wu, G., Xiong, Z., Chua, Y.S., Chen, P. (2008-07-08). Improvement of hydrogen storage properties of the Li-Mg-N-H system by addition of LiBH4. Chemistry of Materials 20 (13) : 4398-4402. ScholarBank@NUS Repository. https://doi.org/10.1021/cm800584x||Abstract:||Significant improvements in the hydrogen desorption/absorption properties of the Li-Mg-N-H system have been achieved by adding a small amount of LiBH 4. The onset as well as the peak temperatures of hydrogen desorption shift to lower temperatures. Five wt % of hydrogen can be fully desorbed at 140 °C and reabsorbed at 100°C. The kinetics of hydrogen desorption as well as absorption were found to be 3 times as fast as the pristine system. Thermodynamic analyses show that the temperature for equilibrium desorption pressure at 1 bar was 70°C, which is about 20°C lower than the pristine system. The enhancement in the hydrogen sorption properties was attributed to the weakening of N-H bonding in the metal amide molecules. © 2008 American Chemical Society.||Source Title:||Chemistry of Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/94009||ISSN:||08974756||DOI:||10.1021/cm800584x|
