| Abstract: | The effect of Mg2CoH5/PrH3 on the microstructure and dehydrogenation kinetics property of Li-Mg-N-H system was studied by X-ray diffraction,scanning electron microscopy,MS and kinetics measurements.The results indicated that the addition of Mg2CoH5/PrH3 enhanced the dehydrogenation kinetics property of Li-Mg-N-H system.The reason is the thinning in the reaction product layer and the catalysis of Co and PrH3 precipited during the reaction process. |
