KMg1−xPdxF3 with Perovskite-Like Structures as Precursors for the Catalytic Hydroconversion of CCl2F2 and CHClF2

Several fluoride type perovskites, with formula KMg1−xPdxF3, have been prepared for the first time. The enlargement of their cell parameters has been associated with the insertion of Pd into the structure. After reduction, these new compounds, when tested in the hydrodechlorination reaction of CCl2F2 and CHClF2, showed higher selectivities to CHClF2 and CH2F2, respectively, than other Pd catalysts supported on KMgF3.
