Catalytic decomposition of N<inf>2</inf>O on La<inf>2</inf>Cu<inf>0.5</inf>M<inf>0.5</inf>O<inf>4</inf> (M=Co, Ni, Cu and Zn)

Decomposition of N2O has been studied over La2Cu0.5M0.5O4 (M=Co, Ni, Cu and Zn) between 380 and 485°C at 50 torr initial pressure of N2O to understand the mutual interaction of two different active metal ions of the same concentration and valence in deciding the physico-chemical and catalytic properties. A multicenter type of adsorption of N2O has been visualized and it is found that the rate is governed by the electronic factor. © 1991 Akadémiai Kiadó.
