摘 要：Magnesium nanoparticles were synthesized by using organo magnesium precursor. By changing synthesis parameters such as synthesis time and temperature, various morphologies of the magnesium nanoparticles were obtained. Sample synthesized at 250℃ for 30 min exhibited agglomerated nano-sheets of magnesium whereas the sample obtained at 2 hour had individual particles consisted of core/shell structure. The corresponding hydrogen storage properties of these samples were also influenced by the morphology. Hydrogen desorption data revealed that samples prepared at 2 hour could release hydrogen at lower temperature (343℃) than those samples prepared at 30 min and 1 hour.
