Preparation of Fibrous SO₄^2-/ZrO₂-Nio Solid Acid Catalyst, Characterization and its Catalytic Properties

Abstract:

A novel SO₄^2-/ZrO₂-NiO solid acid catalyst was prepared by using collagen fiber as the template. It was found that the SO₄^{2-//sup>ZrO₂-NiO catalyst remained good fibrous morphology by scanning electron microscopy (SEM). The IR analysis suggested that the metal oxide surface and SO₄^2- were combined to form dual-coordinate state. The catalyst had both medium strong acidic sites and strong acidic sites through temperature-programmed decomposition (TPD) of ammonia. The calcination temperature is inversely proportional to the surface area of fibrous ZrO₂-NiO. The catalyst was applied to the esterification of acetic acid with n-butanol to estimate the catalytic activity and the best preparation conditions of SO₄^2-/ZrO₂-NiO solid acid catalyst was found out. The results showed the SO₄^2-/ZrO₂-NiO catalyst had high catalytic activity.}
