Synthesis and physicochemical and catalytic properties of perovskites ABO(3 +/- y) (A = La, Sr, Ag; B=Mn, Co, Fe, Cu, Ti, Mo, V)

The effect is considered exerted by synthesis conditions and composition of complex oxide materials ABO(3+/-y) based on d metals (Mn, Co, etc.) with p erovskite structure on their catalytic activity in CO and Il-heptane oxidat ion. The possibility of using such an empirical parameter as the content of active oxygen for prognosticating catalytic properties is evaluated. Neutr on diffraction analysis was applied to determine the structure of the compl ex oxides and characteristics of particles of these materials.
