Mesoporous SiO2–Al2O3 supported Cr2O3 catalysts were prepared by the sol–gel and impregnation methods. These catalysts were characterized and applied in cyclohexane nitrosation reaction. The effects of the preparation conditions and the catalyst deactivation were studied. The results show that 20% Cr2O3/SiO2–Al2O3 catalyst calcined at 400 °C exhibits not only the larger surface area, smaller particle...
