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 PdCuClx intermediate, which can easily migrate to a nearby catalyst surface and then be reduced to smaller PdCu NPs.
