Abstract
ABO(3) perovskite (A = Ca, Sr, Ba; B = Ti, Zr) has been prepared by a sol-gel method from oxygenated (I) or chlorinated (II) precursors. The difference in C-2-hydrocarbon selectivity depending on the preparatio n mode is ascribed to the presence of chlorine. To understand the effe ct of chlorine, the various catalysts have been characterized by XRD, BET, O-2 temperature programmed desorption. Addition of organic chlori nated compounds as probe molecules have been studied and compared on c atalysts I and II.
