ZrO_2 is a catalyst support with good chemical stability, oxidation-reduction properties and acidity-alkalescence on its surface. ZrO_2 can interact rather intensively with active phases, and has extensive applications in hydrogenation, synthesis of F-T and oxidation reaction. Nano ZrO_2 has high specific surface area and its surface defects is rich, but nano ZrO_2 particles are prone to agglomerate and reduce the specific surface area under high temperature. This dissertation takes the route of the followi...
