LnFeNi(Ru)O3 perovskites synthesized via a modified Pechini method have been studied as catalyst precursors in CO2 reforming of methane. The structural and redox properties along with catalytic performance were found to depend upon Ln nature and Ru content in the perovskite. Active and stable catalysts have been formed from perovskite precursors in reaction media at high temperatures due to Fe–Ni–(Ru) alloy particles segregation from the perovskite lattice and their stabilization on the oxide surface. Coking stability of these catalysts in dry reforming of real natural gas containing admixtures of higher hydrocarbons is explained by combined effects of Ni dilution by Ru in alloy nanoparticles and high mobility and reactivity of surface/lattice oxygen in the disordered Ln ferrite support.
