Abstract

The heterometallic complex [RuNO(NO₂)₄OHNi(En)₂] was prepared by the reaction of [RuNO(NO₂)₄OH]²⁻ with Ni²⁺ in the presence of a small excess of ethylenediamine. According to single-crystal XRD, the ruthenium fragment is coordinated to the nickel atom through μ-OH and the bidentate (N, O) nitro-ligand. Bidentate ethylenediamine ligands complete the coordination sphere of nickel. The thermal decomposition of the complex in reductive atmosphere with the heating rate of 1 K min⁻¹ allowed the preparation of a single-phase Ni_0.5Ru_0.5 solid solution. The crystallite size of the prepared nanoalloy varies in the range of 21-29 nm. The catalytic properties of the prepared nanoalloy in the CO methanation reaction closely resemble those of pure nickel. Yet, in the side reaction of CO to CO₂ oxidation, the Ni_0.5Ru_0.5 solid solution demonstrates greater activity in the low-temperature range.
