- Аннотация: Oxide precursors NdCaCo1-xNixOn (x = 0; 0.2; 0.4; 0.6; 0.8; 1) are obtained by the solid state synthesis method at 1100C. According to XRD analysis, the main components of these precursors are complex oxides with K2NiF4-like structure at x 0.8 and with rhombically distorted K2NiF4 structure at x = 1. A thermal decomposition of these precursors in the mixture of CH4/O2 = 2 at T 800C results in the formation of dense metal-oxide nanocomposite particles. As-obtained nanocomposites demonstrated a considerable catalytic activity and selectivity in the reaction of partial oxidation of methane; their catalytic properties vary non-monotonously with Co/Ni ratio. The maximum CH4 conversion and CO selectivity at 820C is demonstrated by the composite comprising Nd2O3, CaO, NiO and Ni metal nanoparticles.
