CuCl 2 on γ-alumina, the base catalyst for oxychiorination reactions, has been investigated by several techniques as a function of Cu loading, sample aging and heating. The results point out the formation of a surface Cu aluminate species and a highly dispersed CuCl 2 . The latter slowly hydrolyzes under aging, but CuCl 2 is restored under heating and is the active species in oxychiorination as demonstrated by activity tests.
