Abstract
Perovskite catalysts of the type La2MnMO6 (M Co, Ni, Cu) were synthesized by means of a ceramic technique. Single-phase formation was checked by means of X-ray diffraction using Cu Kα radiation. Electrical conductivity measurements were carried out with a standard two-probe cell. The catalytic activity of the perovskites was tested for the decomposition of 2-propanol in the temperature range 200–300 °C in a fixed-bed flow type of reactor. All the perovskites promote dehydrogenation of the alcohol. A possible mechanism for the reaction is proposed by studying the effect of products on the reaction rate and from the variations in the electrical conductivity of the pelletized catalysts in the reactant and product atmospheres.
