Hydrogen-assisted dehydrochlorination of 1,1,1,2-tetrafluoro-2-chloropropane to 2,3,3,3-tetrafluoropropene over Pd-Ag/nano-MgF2 with optimized Pd isolated sites Communications Chemistry, Published online: 14 January 2026; doi:10.1038/s42004-026-01896-wHydrogen-assisted dehydrochlorination (HaDHC) is an attractive route for the production of fluorine-containing olefins under relatively mild conditions, but highly efficient metal-based catalysts for this reaction remain underexplored. Here, the authors report a nano-MgF2-supported Pd-Ag catalyst with tunable Pd dispersion that is optimized by tuning of the Pd-Ag alloy degree in the fresh catalyst, followed by in situ restructuring, and demonstrate its performance in the HaDHC of 1,1,1,2-tetrafluoro-2-chloropropane (HCFC-244bb) to 2,3,3,3-tetrafluoropropene (HFO-1234yf), a hydrofluoroolefin refrigerant with reduced global warming impact. http://dlvr.it/TQLN0Q
