| 摘要: 借助于一种全新的表面活性剂N，N-dimethyloctadecylammonium bromide acetate sodium（OTAB-Na），成功实现了对小尺寸钯纳米粒子微结构的控制。通过对合成条件的微扰，高度均匀且分散性良好的枝化结构和凹面体结构的钯纳米粒子被成功地制备。催化测试（利用氨硼烷作为氢化试剂来还原4-硝基苯酚为4-胺基苯酚）发现，钯纳米粒子的催化活性与其微观纳米结构相关，其中枝化结构的钯纳米粒子表现出了更为突出的催化性能。 | |

| Abstract: A morphology-evolution of Pd nanocrystals was successfully triggered by using N,N-dimethyloctade-cylammonium bromide acetate sodium (OTAB-Na) as the capping agent. Uniform and monodisperse dendritic and concave Pd nanocrystals were synthesized by directly changing the pH value of the reaction solution. In the following catalytic test of liquid-phase reduction of 4-nitrophenol (4-NP) by ammonia-borane complex (AB), the as-obtained Pd nanocrystals exhibit a shape-dependent catalytic properties, in which the dendritic nanosphere is the better one. | |
