La1− xAxNiO3− δ (A= Pr, Ce) perovskites were synthesized by the auto-combustion method
and evaluated as catalyst precursors in the dry reforming of methane. After reduction of the
perovskites the average diameter of Ni° on the catalysts LaNiO3, La0. 9Ce0. 1NiO3 and
La0. 9Pr0. 1NiO3− δ were: 15nm, 9nm and 6nm, respectively. Catalysts obtained by the
reduction of the perovskites had the highest catalytic activity under drastic reaction
conditions (10mg of catalyst and a mixture of CH4/CO2 without dilution gas) compared to …
