制样是制备高质量电镜样品照片的关键一步。关于催化剂的电镜样品制备方法,根据不同对象和要求而异。本文介绍一种模型催化剂的电镜样品制备技术,即所谓高频溅射沉积法,由此法所制得的样品电镜图象非常清晰,可用来研究催化剂在热处理过程中金属粒子的变化规律和形成物相的特征。
Sample preparation is a key step in producing high-quality electron microscopy sample photos. Electron microscopy on the catalyst sample preparation methods, according to different objects and requirements vary. This article describes a model catalyst electron microscopy sample preparation technology, the so-called high-frequency sputtering deposition method, obtained by this method sample electron microscopy image is very clear, can be used to study the catalyst in the heat treatment process of metal particles change and formation Characteristics of the phase.
