Silanized aluminosilicate halloysite nanotubes were used as a support for Pd-Ag catalysts in the selective hydrogenation of acetylene. The catalysts synthesized from [Pd(NH3)4]Cl2 showed the highest selectivity towards ethylene, reaching about 85% at 10-55% acetylene conversion. The samples were characterized by various techniques including low-temperature nitrogen adsorption, ammonia temperature-programmed desorption, and transmission electron microscopy.
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)]Cl-2 as a palladium precursor proved to be the most selective towards ethylene: the selectivity reached about 85% at 10-55% acetylene conversion.
