The effect of Fe addition on catalytic activity and stability of LaNixFe1xO3 perovskitecatalyst was investigated for hydrogen production via steam reforming of tar using tolueneas a model compound. The addition of Fe to LaNiO3 catalyst at the optimum amountenhanced the catalytic performance in steam reforming of toluene. LaNi0.8Fe0.2O3 catalystshows the best performance in terms of catalytic activity and stability for 8 h of reactiontime. The catalyst characterization indicates the presence of Ni-rich NieFe smaller bimetallic particles, strong metal support interaction, and lower carbon deposition rate onLaNi0.8Fe0.2O3 catalyst. The synergy between Ni and Fe atoms on the small NieFe bimetallicparticles is crucial for high activity of the LaNi0.8Fe0.2O3 catalyst. In addition, the stronginteraction between metal and support on the LaNi0.8Fe0.2O3 catalyst can prevent metalsintering, thus, achieving high catalytic stability.
