Selective Hydrogenation of Acetylene over Palladium Catalysts Based on Aluminosilicate Nanotubes
Petroleum chemistry(2022)
摘要
Silanized aluminosilicate halloysite nanotubes were investigated as a support for Pd–Ag catalysts. The samples were characterized by low-temperature nitrogen adsorption, ammonia temperature-programmed desorption, and transmission electron microscopy, and tested in selective hydrogenation of acetylene. The Pd–Ag/halloysite catalysts synthesized from [Pd(NH3)4]Cl2 as a palladium precursor proved to be the most selective towards ethylene: the selectivity reached about 85
