Effect of addition of intermetallic componds on the catalytic activity of La2CuO4

Decomposition of nitrous oxide has been studied on pure La₂CuO₄, La₂CuO₄ with 5 wt.% CaNi₅ and La₂CuO₄ with 5 wt.% NiO in the temperature range 200–480°C at 200 Torr initial pressure of reactant gas. The addition of 5 wt.% CaNi₅ decreases the energy of activation drastically in comparison with La₂CuO₄. The results are explained on the basis of the dispersity of Ni/NiO on La₂CuO₄.
