Abstract

Supported catalysts Ru/MgO, Ru–Cs⁺/MgO, Ru/γ-Al₂O₃, and Ru–Cs⁺/γ-Al₂O₃ are prepared by the impregnation method using RuOHCl₃ and Cs₂CO₃ as precursor compounds, reduced in hydrogen at 450 °C, and characterized by XRD, PDF, and EXAFS. The phase composition and local structure of the active component are determined. In the case of MgO support, the structure of the cesium promoter corresponds to cesium oxides. In the case of γ-Al₂O₃ supported catalysts, ruthenium and cesium ions interact during the synthesis to form aluminates and solid solutions in the support structure.
