    • Abstract

       

      SBA-15, KIT-6, SiO₂ supported catalysts with 10% Cu loading have been prepared by impregnation techniques. The prepared catalysts have been characterized by BET technique, X-ray diffraction, Temperature programmed reduction (TPR), XPS and N₂O pulse chemisorption techniques. Dehydrogenation of cyclohexanol has been performed over these catalysts in vapour phase at 523 K. SBA-15 and KIT-6 supported copper catalystsshowed higher activity than SiO₂ supported Cu catalyst in dehydrogenation of cyclohexanol, which can be attributed to better Cu dispersion, small copper particle size and more number of Cu active species presented on the surface of mesoporous supported catalysts.
