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.",

N2 - 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.
