摘要
本文用JSM-35CF电子显微镜研究了Pd/阴离子交换树脂催化剂的形态及钯在树脂上的分布,考察了催化剂的预还原和使用对钯分布的影响。结果表明:该催化剂中大部分钯都分布于树脂颗粒表面,在表面的分布相当均匀,催化剂的预还原及使用对钯的分布影响较小。
The distribution of palladium in Pd/anion-exchange resin catalysts and surface state of the catalyst were studied by JSM-35CF scanning electron microscope. It is shown that these cat- alysts have suitable surface state and the main part of Pd are well distributed on the surface layer of catalyst pellets. The distribution of Pd in these catalysts are not affected by prelim- inary reduction and usage in reaction.
