Abstract

A novel CFCl₂CF₂Cl(R113)/H₂ gas treatment process was proposed and successfully applied for the redispersion of a sintered alloy PdCu/AC catalyst. The redispersion process was initiated by the formation of an oxidative PdCuCl_x intermediate, which can easily migrate to a nearby catalyst surface and then be reduced to smaller PdCu NPs.
