Magnesium fluoride-supported palladium and ruthenium appear to be useful catalysts in the reaction of CCl2F2 (CFC-12) hydrodechlorination; after doping Pd/MgF2 with gold selectivity for CH2F2 increased from ≡70 almost 90%.
We report an operando XRD/MS experiment on a nanocrystalline Pd(70%)Ag(30%) alloy supported silica (10 wt% of metal) monitoring slow reversible Pd (in CO) and subsequently Ag He) surface segregation at 673 K. XRD data following CO He flow show structural changes that can be modeled interpreted in terms the diffusion phenomena within typical metal nanocluster. Qualitative differences rate both processes suggest different mechanisms as involves vacancy depletion. The experimental details this...
