To clarify the critical size of Pd nanoparticles in which strongly-bound hydrogen can exist, amineprotected Pd nanoparticles were successfully synthesized in the 2-5 nm range by an in-situ homoepitaxial growth of the Pd nuclei. Investigation on hydrogen storage properties of multiplytwinned Pd nanoparticles(15 and 40 nm), single crystalline hexahedral Pd nanoparticles(10 nm), and polycrystalline Pd nanoparticles(6. 6 nm) revealed that the hydrogen storage/release behaviors are greatly dependent on the crystal structure, shape, and size of the Pd nanoparticles and the hydrogen atoms are strongly bound in all particles.

为了阐明强结合氢可以存在的Pd纳米颗粒的临界尺寸，通过原位同质外延生长Pd核成功地合成了2-5 nm范围内的胺保护的Pd纳米颗粒。研究了多孪晶Pd纳米颗粒（15和40 nm）、单晶六面体Pd纳米颗粒（10 nm）和多晶Pd纳米颗粒（6.结果表明，Pd纳米粒子的晶体结构、形状和尺寸对储氢/放氢行为有很大的影响，并且氢原子在所有粒子中都有很强的结合.
