A Novel Method for Preparation of Alumina-Supported Rhenium-Cesium Catalyst, Re-Cs/-Al2O3

Alumina-supported Cs3[Re(C2O4)3] precursor has been synthesized for preparation of Re-Cs/-Al2O3 catalyst. Cs3[Re(C2O4)3] has been prepared from the reaction of ReCl3 with H2C2O4.2H2O and CsCl in water. The complex has been characterized by elemental analysis and various spectroscopy techniques such as FT-IR, UV-Vis and 13C-NMR. The complex was supported on γ-Al2O3 by column chromatography. Cs3[Re(C2O4)3]/Al2O3 was calcined at 600 °C for 6 h. Characterization of both precursor and calcined catalyst were carried out using XRD, BET specific surface area and thermal analysis methods (TGA/DSC).
