This thesis presents optimization of synthesis methods of complex oxide compositions based on nickelates of rare earth elements and alkaline earth metals, obtaining on their basis the new materials with advanced practical use properties. The formation of nonstoichiometric double oxides in systems La-Ni-O, Nd-Ni-O, Pr-Ni-O was explored. The research explored catalytic properties of nickelates, cobaltates, manganates of strontium and barium, doped by ions of alkaline metals in reactions of methane oxidation to ethene. Isomorphic substitution in systems (La, Pr, Nd)3-xMexNi2O7 and (La, Pr, Nd)4-xMexNi3O10 (where Me = Ca, Sr, Ba) was explored.
