Effect of support modification by carbon coverage in the dehydrogenation activity of Cu/Al2O3 catalyst

Gamma alumina and carbon covered gamma alumina supported Cu catalysts were prepared and characterized by adsorptive decomposition of N2O, NH3 chemisorption and temperature-programmed reduction. The decrease in interaction of copper species with alumina of carbon covered alumina has influence on the...

Summary:Gamma alumina and carbon covered gamma alumina supported Cu catalysts were prepared and characterized by adsorptive decomposition of N2O, NH3 chemisorption and temperature-programmed reduction. The decrease in interaction of copper species with alumina of carbon covered alumina has influence on the conversion and selectivity of the reaction of cyclohexanol to cyclohexanone.
