纳米材料的性质和纳米微颗粒的形状、大小和分布有密切的关系。因此深入研究纳米材料的显微结构,了解其结构特征,以便为制备纳米材料时有效地控制纳米颗粒的大小、形状和尺寸分布提供必要信息。我们用JEM-2010FEF场发射能量过滤透射电子显微镜对Pd-Al2O3催化剂和金纳米颗粒、单
The properties of nanomaterials are closely related to the shape, size and distribution of the nanoparticles. Therefore, in-depth study of the microstructure of nano-materials to understand its structural features in order to prepare the nano-materials to effectively control the size, shape and size distribution of nano-particles provide the necessary information. We use the JEM-2010FEF field emission energy transmission electron microscopy of Pd-Al2O3 catalyst and gold nanoparticles, single
